I want to change / update the mobile number on which I receive the verification code sent by Google by SMS. However, I am unable to do so despite careful analysis of the Google Account settings.
I can change / update the new number, and the old number is no longer visible anywhere in my Google Account settings, I still receive the verification codes by SMS on the previous number.
I even tried to wait a few days to see if the server started to record the new / updated number but to no avail.
I have activated 2FA on my account in question and I am using a third party application to generate the 2FA codes (1Password). I don't think it should make a difference and I haven't tried to disable it.
Is there something missing here? Or could it be a possible bug? How do I completely unlink the old number from my Google Account?
