Recently, I have been added to a Teams group that requires authentication to get in as a visitor, after scanning a QR code shown on the web by the authenticator app, i was successfully logged in to Teams which the authenticator appears to have some code after my email name.
However, after I accidentally deleted that authenticated account in the app, I could not receive the notification in the app to choose the correct number. At the same time, the name of the email appears to be my original email name without thing after the ".com" .
What should I do?
