Hi. I used the app with no hassles for a few days, today as soon as I want to enter my password, I receive a pop-up screen prohibiting me to enter with password. The message "Screen overlay detected. Certain full screen apps, such as dimmers, can compromise your security. To continue using the Banking App please disable these in Settings>Apps."

Firstly, why is this happening how all of a sudden. 2 What apps do I have to disable, I have quite a few. This is frustrating as I have to make urgent payments as I'm on the road during the day, this method of payment via the app makes life easier, but now this! 

PLEASE HELP!

regards

Brandon
