I know believe that this is an Apple issue with their last few updates. My ipad never froze before. I actually did a complete reset to factory new, Set it up again but did not load any of my previous apps or files and when I opened safarie to the internet on ebay, it was still freezing and stalling. By the way, I fave fast wi-fi here a home, so that is not it.
So I also took a brand new Air 2, set it up and it does the same thing both at home and on the 4G away from home. I feel that app,e is ignoring this problem and in my case it seems to be getting worse. But mostly on the internet.
I also have purchased a ne Lenovo 12" tablet with Windows 10 and it wotks great, no stalling on anything.
You need to wake up apple and fix this!!!!!!!!!! 😱
