Answer to: iPad Pro 12.9 touchscreen is unresponsive from time to timeSo glad to see the same issue reported here. It feels like proof it’s not user error. I took my iPad to Apple and their reply is that there’s nothing wrong. However, their test was placing it flat on the table and touching several keys. Of course the issue didn’t present but from reading the posts, I too have noticed that it acts up while holding it or at other angles. Only way to fix key lock is move pad back and forth like a reload to a shotgun. It lasts about 3 minutes and problems start again. I’m going back to Apple with this, by armed with a video I took of me attempting to use iPad and screen failing consistently.
