I don’t have a unresponsive touch screen. If you watched my video you would’ve known this and seen my touch screen always always works. Sometimes you can touch a letter, it clicks and lights up, but doesn’t type in the sentence. Several other people are having this problem, it doesn’t affect normal function. And the problem can go unnoticed as it took me 8 days to realize something was up. Problem occurred on (2) identical iPad Pro 11” models. The screen always recognizes touch though, whether or not the OS decides to act on that touch is another thing. This is most likely a iOS issue. As a reset and update alleviated the issue for the most part. Never had a issue any other time though, other than typing when this problem would occur previously. And it has never affected games!
