how can I recover 2FA activated account

Question

My account's 2FA information was saved on my old phone and my phone was reset without my knowledge. I no longer have this 2FA access. I choose the SMS recovery option, enter the information, then it asks for the 25-digit recovery code, I choose no because I don't have it. The next step is "Submitting request We're not ready for you yet, your account is unable to complete the request." error and cannot initiate the 30-day standby phase.

You can restore from backup (assuming there was one) but make sure no accounts have been added to the newly install app. Then sign on with recovery account to do the restore.

You can recover your account credentials from your cloud account, but you must first make sure that the account you're recovering doesn't exist in the Microsoft Authenticator app. For example, if you're recovering your personal Microsoft account, you must make sure you don't have a personal Microsoft account already set up in the authenticator app. This check is important so we can be sure we're not overwriting or erasing an existing account by mistake.
