I don't know if it is my problem (I won't use it) or his problem.
I had no get help, I had let my friends help me. They also failed.
Ask the official, only official automatic reply.
So I gave up the Google validator.
Only use 2FA verification , is phone or email or telegram.
Many website 2FA use Google validator, that website Convenience, but We will be troubled in the future
Because Google validator doesn't recovery me, my friend has failed, no one has recovered successfully.
