Most of the iPad Pro models that got affected by this got this touch issue sometime very early in the iOS 12 update cycle and have NOT been able to fix it or come up with a fix or solution since.
iPadOS 13 has done nothing to mitigate this issue.
And now after you just upgraded directly from some version of iOS 12 directly to iOS 13.1.3, your 2017 iPad Pro, for yet NO reason, have come down with the exact same intermittent, unresponsive touch screen issues every other iPad Pro affected user has been suffering with, for, at least, the last 7 or 8 months, or more.
This is just strange.
Some thing bad is just going on here as this issue continues to be a random event that ONLY affects certain iPad Pro models across all iPad Pro model years!
I am wondering if this is some combination of an iOS software issue and some third party app/s compatibility as this issue does NOT affect every single iPad or iPad Pro ever made by Apple.
I am REALLY confused/confounded about this now, but your iPad Pro just coming down with this touch screen issue, NOW, could be an abberation, an exception to the what has been common to this issue, to date, up until now.
I just do not understand what hardware/software issue/s are at work here, now!
Until Apple can figure this out, I may never get to upgrade my iPad Pro, ever again!
I do not want my iPad Pro to come down with this “incurable” touch screen problem!
