Side button - Assistive touch
The problem started when I went to the AppStore and I wanted to confirm with Face ID, but the AppStore said I needed to activate assistive touch for me to do that. I then went to the accessibility menu and activated assistive touch and now I can download things without a problem. Except, now I have the assistive touch circle on my screen (which I don’t want) and the side button lost its double click function. Please help
