Android 11 January security patch just installed. Now App Lock doesn’t recognise my fingerprint to unlock apps. I have to enter pin. My fingerprint does work for the Norton App Lock itself (ie in order to access the app in order to set which apps will be locked). Have uninstalled Norton App Lock and reinstalled but same result. Pixel 4a 5g

It appears that the update to the Pixel devices has affected the fingerprint feature. Please report this issue to the manufacturer as the other user have. The more reports they get, the faster they may address the issue.
