Issues with Uploading Media Sets and Disappearing Chats in AIP Threads

My team has been encountering a few persistent issues that we need assistance with in AIP Threads:

Errors Uploading Media Sets: Many end-users have reported errors when trying to upload any kind of file with “Upload documents.” For some users, the only beneficial workaround we’ve found is to clear the “cache,” specifically all the media sets previously uploaded under “My Files.” Can anyone provide guidance or a more permanent solution for this issue, since more users are experiencing it as we continue using the application?

Indefinite Chats Disappearing: We’ve noticed that some indefinite chats are disappearing. Users are changing the default to indefinite before starting conversations, but some chats are missing when users return to continue them. Is this a known issue, and are there any recommended steps to prevent this from happening?

“Search for Documents” Feature Update: Lastly, I was wondering if there is any update on the “Search for documents” feature in AIP Threads. We were shown a demo and I am curious if there is any update on its release.

Thank you!
