Question
Can't enable 2FA — it keeps saying "Invalid PIN, please try again"
I am unable to re-enable two-factor authentication on my account.
After getting a new phone, I logged in with a back-up code and disabled 2FA. Now, every time I try to re-enable it, I get the “Invalid PIN, please try again.” error (error response is code: 'InvalidArgument', desc: 'failed to validate authenticator 2FA method'
).
Am I doing something wrong?

Same here, but the phone is not even new. Suddenly Google Authenticator’s codes just stopped working. Thus I tried to re-enable 2FA which led finally this “Invalid PIN, please try again” problem.
