Fixed Issues

$ #44007
PROPOSAL:

Tests

  • Verify that no errors appear in the JS console
  1. Log into Expensify with two accounts on web + a different device or incognito tab.
  2. Open a 1:1 conversation between the two accounts
  3. Disable the internet connection of the first Expensify session in the DevTools (Network -> Throttling -> Offline)
  4. Send messages from the second account to the first account
  5. Enable internet again in the first session (Network -> Throttling -> No throttling)
  6. There should be a "New" (unread messages) marker above the first message that was sent while the user was offline

Offline tests

The description in "Tests" is already covering offline behaviour.

QA Steps

  • Verify that no errors appear in the JS console

Same as in Tests.

PR Author Checklist

  • I linked the correct issue in the ### Fixed Issues section above
  • I wrote clear testing steps that cover the changes made in this PR
    • I added steps for local testing in the Tests section
    • I added steps for the expected offline behavior in the Offline steps section
    • I added steps for Staging and/or Production testing in the QA steps section
    • I added steps to cover failure scenarios (i.e. verify an input displays the correct error message if the entered data is not correct)
    • I turned off my network connection and tested it while offline to ensure it matches the expected behavior (i.e. verify the default avatar icon is displayed if app is offline)
    • I tested this PR with a High Traffic account against the staging or production API to ensure there are no regressions (e.g. long loading states that impact usability).
  • I included screenshots or videos for tests on all platforms
  • I ran the tests on all platforms & verified they passed on:
    • Android: Native
    • Android: mWeb Chrome
    • iOS: Native
    • iOS: mWeb Safari
    • MacOS: Chrome / Safari
    • MacOS: Desktop
  • I verified there are no console errors (if there's a console error not related to the PR, report it or open an issue for it to be fixed)
  • I followed proper code patterns (see Reviewing the code)
    • I verified that any callback methods that were added or modified are named for what the method does and never what callback they handle (i.e. toggleReport and not onIconClick)
    • I verified that the left part of a conditional rendering a React component is a boolean and NOT a string, e.g. myBool && <MyComponent />.
    • I verified that comments were added to code that is not self explanatory
    • I verified that any new or modified comments were clear, correct English, and explained "why" the code was doing something instead of only explaining "what" the code was doing.
    • I verified any copy / text shown in the product is localized by adding it to src/languages/* files and using the translation method
      • If any non-english text was added/modified, I verified the translation was requested/reviewed in #expensify-open-source and it was approved by an internal Expensify engineer. Link to Slack message:
    • I verified all numbers, amounts, dates and phone numbers shown in the product are using the localization methods
    • I verified any copy / text that was added to the app is grammatically correct in English. It adheres to proper capitalization guidelines (note: only the first word of header/labels should be capitalized), and is either coming verbatim from figma or has been approved by marketing (in order to get marketing approval, ask the Bug Zero team member to add the Waiting for copy label to the issue)
    • I verified proper file naming conventions were followed for any new files or renamed files. All non-platform specific files are named after what they export and are not named "index.js". All platform-specific files are named for the platform the code supports as outlined in the README.
    • I verified the JSDocs style guidelines (in STYLE.md) were followed
  • If a new code pattern is added I verified it was agreed to be used by multiple Expensify engineers
  • I followed the guidelines as stated in the Review Guidelines
  • I tested other components that can be impacted by my changes (i.e. if the PR modifies a shared library or component like Avatar, I verified the components using Avatar are working as expected)
  • I verified all code is DRY (the PR doesn't include any logic written more than once, with the exception of tests)
  • I verified any variables that can be defined as constants (ie. in CONST.js or at the top of the file that uses the constant) are defined as such
  • I verified that if a function's arguments changed that all usages have also been updated correctly
  • If any new file was added I verified that:
    • The file has a description of what it does and/or why is needed at the top of the file if the code is not self explanatory
  • If a new CSS style is added I verified that:
    • A similar style doesn't already exist
    • The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(theme.componentBG))
  • If the PR modifies code that runs when editing or sending messages, I tested and verified there is no unexpected behavior for all supported markdown - URLs, single line code, code blocks, quotes, headings, bold, strikethrough, and italic.
  • If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
  • If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
  • If the PR modifies a component or page that can be accessed by a direct deeplink, I verified that the code functions as expected when the deeplink is used - from a logged in and logged out account.
  • If the PR modifies the UI (e.g. new buttons, new UI components, changing the padding/spacing/sizing, moving components, etc) or modifies the form input styles:
    • I verified that all the inputs inside a form are aligned with each other.
    • I added Design label and/or tagged @Expensify/design so the design team can review the changes.
  • If a new page is added, I verified it's using the ScrollView component to make it scrollable when more elements are added to the page.
  • If the main branch was merged into this PR after a review, I tested again and verified the outcome was still expected according to the Test steps.

@roryabraham @chrispader Do you think we should work on the marker dismissal here? I can only dismiss if I enter another conversation and come back:

If so, i think this should be handled in a separate issue. The same behavior is the case for receiving messages in a report when it's not active. (also the case on main).

I understand, I also agree that taking this to another issue would be more appropriate.

@chrispader I'm having problems with the marker, I'm "playing around" with two conversations and the behavior is still not consistent in my tests:

Screen.Recording.2024-09-23.at.12.19.21.mov

I'll come back here tomorrow and test more, I'll clean everything up here, maybe it's something with my local. But, in your tests, did everything work correctly? Thank you.

One thing that makes me wonder: Why did the right user receive the message from the left one before throttling was disabled (before it went back online)? That's weird.

I can see that the users own messages are als recognized as "new messages". This shouldn't happen. I'm going to look into that!

Other than that, i had no problems with the unread marker while testing

@chrispader Indeed, sorry, ignore that report, it was an issue with my local. I tested the changes in all platforms, it seems fine so far. Did you have a chance to check "I can see that the users own messages are als recognized as "new messages". This shouldn't happen. I'm going to look into that!"? Thank you.

Solution

This logic has no control of whether the message has (actually) been created/sent while the sender was offline. Only messages received while the own device was offline will be "marked as unread" (green line).

Therefore, we have two options on how to handle this in the UI.

Approach 1

Stick with the current implementation and only mark messages as unread, that have been received while the current user was offline. In case both users are offline while sending message, the user who is back online first will not see the "urnead marker".

Approach 2

Also mark messages as unread, that have been created while the sender was offline. For this, we will need to add an additional prop like createdWhileOfflineAt or wasCreatedWhileOffline to keep track of whether the message was created in an offline state.

I don't favor this approach though, since this would also mean, that all (online) users will receive "unread markers" (green lines) if some other user sends a message while offline. This might be very disturbing in groups especially.

Curious about your thoughts cc @brunovjk @tylerkaraszewski

Thanks for the detailed explanation, @chrispader. Apologies for any unnecessary extra work on this. I believe this is primarily an edge case and not reflective of typical user behavior, though I can't confirm that definitively (we'd need @tylerkaraszewski's input on that). From my perspective, we can proceed as is to avoid regressions.

I've read the scenario above and particularly point 9 is of interest:

User A will receive a message from User B with created timestamp 8. User A will not see the green line, because User A was already back online at 8.

This says that user A receives a message while online and thus the green line is not updated.

I think that's fine, I don't think user A needs to care if user B was online or not when they initially tried to send it. When the message is actually able to be sent, user A is online, and the message arrives immediately.

I think that's fine. That lets us go with the current solution, correct?

This says that user A receives a message while online and thus the green line is not updated.

Correct, technically the message is received while already back online. (Only) if both devices come back online at the same time, it might be perceived as weird, but i suppose no user will ever use two devices at the same time and text himself.

I think that's fine. That lets us go with the current solution, correct?

Yes, that sounds good!

Coming from #55990. We missed a case here, where if you received a message from a chat that's not open, then go offline and open that report, the new message marker won't show. This is because lastOnlineAt will be undefined here as it's stored in component state. More details.
