All apps disappear on iPhone 11
I have had my new iPhone 11 about six weeks. Periodically, maybe about every two weeks or so, ALL my apps suddenly disappear from the screen. Every single one, except the four in the "dock" at the bottom. I am left staring at the smoky background. When I turn my phone off and back on, they all reappear. What can I do to prevent this? I can't find any reference to the problem anywhere.
