Out of the blue- G3 asks for PIN to unlock...
Knock codes working fine most of the time.
Just checked some email.... took a phone call.
After the phone call ended, there's a screen asking me to enter my backup PIN code or sign in with my Google account. I cannot "go back" or get out of it until I enter PIN, reset knock code, etc.
Why? Has anyone run into this?
