Show or Hide apps option in the MDM settings. You must have enterprise for this to work fyi. If not you can also do single app mode which will only allows one app to open, full screens it, and you cannot back out of it. Hope this helps.
Well let's say you do single app mode. When the policy kicks in it will only have the "single app" you chose and you can't do anything. Example: Calculator app. Unless the child loves solving math problems that's all they get.😂
@BlakeRichardson they can if they know the reset function but if an app is on single app mode they can't even go to settings but to your point if they do the "home""power" button then they can reset in itunes. So yeah.
