iPad keeps cutting off and back on
ipad has been updated to ios 15.4.1, but keeps cutting off and back on (it says hello, as if it’s new and Im setting it up when it comes back on) as if it has just updated while Im iusing it. Then it says I need to activate my iPad and sign in with my Apple ID and password to use it. Why is this happening and how do I resolve it?
