Removing all references to Teams in Credential Manager seems to resolve the issue. However, it should notice a new password sync issue and prompt you to re-enter, which it obviously does not.
The team continues to make progress on this. We will share more details as we have them.
Improvements to day/work week/week view are in the public ring. Our focus now is a new scheduling experience and scheduling assistant, appointments and more.
