I open Grab apps also sometimes go window pop up asking me to rekey in my password and thumbprint so I will not forget.

But too busy to read so I got do it.

Lucky so far nothing happen.
I unlink all my auto top up and banks to all apps, except Sony PlayStore.

Some popular apps also Sohai one, no give option to pay using Online banking. All need to link with bank, debit/credit card one.
