OleksiiI don't have a Zenfone, but please bear with me if I get this wrong.
I encout with a problem two applications (maybe more) somehow logout by itself.
First one banking app (Bank of Melbourne) does not 'like' fingerprint sensor. Each time I return to the app it askes me to go through the full process of login (which insanely painful), instead of asking fingerprint (even though I chose it in settings)
The second: Binance. It just logged out by itself. And it's the same painful to login again.
What's happening with apps?
Logout apps by itself
