I am also getting error from Google Pay that it is not set. I have not tried paying, but the error still stands.
But I am experiencing one huge issue. When I restart my phone and unlock pattern has to be drawn after reboot, the pattern does not work. For wrong pattern, the phone informs that the pattern is wrong, but with correct pattern, nothing happens. After many restarts, power off - power on and pattern attempts, the pattern is accepted so the pattern passing rate is somewhere 10%.
