iOS 11.3.1. It seems that my 2 year old 2016 iPad Pro has become unresponsive to touch. I frequently have to touch buttons multiple times for them to register and swiping and scrolling is generally a pain. It’s almost as if the software is too cpu intensive and it makes the iPad lag. I have reinstalled iOS 11.3.1 and restored as a new iPad and that did not fix the issue. Has anyone else experienced issues like this on a 2016 iPad Pro 12.9 and if so, how did you fix it? It seems the issue has sprung up since iOS 11.3 or maybe 11.3 is the software version when the screen started breaking, who knows. Thanks in advance for any guidance.
