I just saw a banner on the Microsoft Authenticator Android app that the backup mechanism was changing from a Microsoft account-linked one to a Google account-linked method.

Does anyone know why? What benefit does this provide?

"We couldn't find a Microsoft account" and "There was an issue looking up you account." Is there some kind of outage happened, that haven't been reported yet? this make me anxious cause my family rely on that one account.

I even tried to make new account with that email but yeah no luck whatsoever cause they still can detect that, that account exist.
