I don't know why but since yesterday my ipad has been acting up. It automatically updates itself and I'm unaware if it updated recently to cause this change. When I turn it on and put in my passcode, it freezes,unlocks and then goes to my main screen. When the main screen appears, it freezes and I cannot do anything for about 5 minutes. This has been happening since yesterday I do not know why. Is this happening with anyone else other than me?
