Azure AD Join issues

We have started to receive since Friday with a varied number of issues with Azure AD Join deployment task. Essentially most of our tenants have arbitrarily stopped working.
Ive tried support with little success.
Some tenants have received AADSTS90002: Tenant not found. Verified the service principal is present. I ran the immybot update to address it but that is still problematic.
Other tenants have received ```
0xCAA90004 Getting token by refresh token failed

AADSTS50173: The provided grant has expired due to it being revoked, a fresh auth token is needed. The user might have changed or reset their password. 
We have tried reauthorization and it seems to not be processing successfully. 
If there are any suggestions from the group here any suggestions would be appreciated.

If you are using the OAuth flow, try switching to Username/Password
