Hello @syang234,
Yes, we discussed the issue in the thread.
Microsoft released an update that affected our app, too. We contacted them and received a response that they will include the fix in the next-week deployment cycle. This means that, depending on the tenant region and Microsoft deployment order, it will take from one to four weeks to resolve the issue for different users.
In the meantime, please use the Documents custom connector
Best regards,
Petr
