Hi @Steven Asher,
Thank you so much for getting back to us and for sharing these additional details. I’m really sorry to hear that none of the previous steps resolved the issue.
I understand the issue with the “The destination is being set up” message still persists when trying to reuse assignments in newly created Teams classes. Since the usual troubleshooting steps (waiting, clearing cache, switching devices/platforms) haven’t resolved it, here are some deeper insights and next steps:
1/ Use web browser as a workaround
Some users have successfully bypassed the issue by using Teams on the web instead of the desktop or mobile apps. [learn.microsoft.com]
2/ Open a Microsoft Support Ticket
If the issue persists across platforms and time, it may require backend intervention. Please open a support ticket via the Microsoft 365 Admin Center so the engineering team can investigate provisioning logs.
I truly appreciate your patience and understanding while this gets sorted out. Please let me know if there's anything else I can help you with.
Again, I’m really sorry for the inconvenience this has caused. Thank you for bringing this to our attention and for working with us to get it resolved.
