Block buttons in App
I remember being able to go to my Settings and choosing a function which would 'block out' a button or a section of an iOS App ... so that it would not activate or be able to be chosen in that App.
I could 'circle' the button or function ... and whatever was inside the circled area would be non-functional, namely the button would not activate, unless I used my passcode for doing that.
I don't remember how to do that and don't seem to be able to find it.
Does anyone know or remember how to do that?
