Authenticator: Unexpected error. Please contact your local IT administrator to resolve the problem

Question

Got a new Pixel/Android phone, recovered authenticator app codes from backup. Some accounts were showing errored or need more info.

1st issue:

Couple of accounts I was able to recover, some others have to register MFA again, luckily i still had my old phone, if it was lost account access to those would have gone. Backups work partially.

2nd issue:

Some more other Microsoft and Entra accounts I am not able to use Microsoft authenticator App for MFA registration. Getting error "Unexpected error. Please contact your local IT administrator to resolve the problem"

I am the admin of my personal account, how do I solve this.

I am also admin of my work Entra and i donot see any logs for MFA registration failure that would help. Audit logs only show successful registration. Also do not to set require registration of MFA in Entra as same issue happening with personal account. Although it seems more like app issue.

Other steps taken

• I have tried deleting app data, forcing to re-authenticate, when recovering from backup.
• I have uninstalled app and did not try recovering, I don't get any previous MFA accounts but also still not able to register authenticator app for both personal/work accounts.
• I have uninstalled app and did not try recovering, Used another account to signin to authenticator. I still cannot register authenticator app for both personal/work accounts.
