Pixel 4 XL
I enabled App Lock and am able to unlock the app using face unlock and the app functions correctly as long as the app remains in the foreground. If I switch apps for even an extremely short period of time the app locks up and I have to close the app and re-open it for it to work again. This behavior does not happen at all when App Lock is disabled.
Anyone else experience this on Pixel 4 or possibly other phones?
