I'm getting the following error message.
Failed to execute Skype backend request GetThreadsS2SRequest
when trying to Add, Update or Delete channels using MS Graph API for Teams. The calls were working fine for a while but now suddenly this error comes up. This happens particularly when the channel type is private. Any help would be much appreciated. Thanks.
