+Effective September 1, 2023, Box is discontinuing support for Internet Explorer 11 (IE 11) in Preview SDK. If your application requires IE 11 support, we recommend using the release versions of Preview SDK that were made available before August 15th, 2023. Our team will address any critical blocker and security issues specifically related to IE 11 until October 15, 2023.
