yes it is. just realised what the problem is. I type by swiping. in order for this to work, swipe to type needs to be turned off

Have you been able to try and add the fingerprint while your phone is in safe mode? You can get your device into safe mode by following these steps: -Hold power button until the 3 options of power off, restart, and emergency mode appear-On-screen tap...

have you tried deleting your fingerprint and adding them again?

I think they're updating by batches

it should come soon
