This unresponsive touch issue affects ALL iPad Pro year and modes. NOT just the new 2018 year iPad Pro models.
And that link you supplied is another support site that has no direct affiliation with Apple or Apple monitors or communicates with.
These Apple product support communities are supplied by Apple to allows a combination of Apple products users and some Apple product specialists, assigned to the user to user Apple product support communities, to help out other users here when needed.
Due to privacy issues and the veracity of the comments here, in these supoort communities, Apple support personnel are not allowed to just simply forward data from the postings posted here.
There is no one in ANY of these Apple Support Communities from any Apple product teams, ever present, here, in these support communities.
Cognizant or responsible Apple product teams, designers and engineers do not read, nor participate in these, largely Apple product user to user technical support communities.
Cognizant Apple teams do not monitor these Apple user support communities, either!
Apple does not know, on its own accord, of any product issues unless customers return product feedback through Apple’s Website.
The only way to get Apple to, DIRECTLY, listen to anyone is to use their feedback portion of their website.
I supplied all of this info two postings/replies above yours.
The feedback numbers have to be large enough for Apple to look into a possible product issue/s and start implementing a fix for a future iOS update.
The feedback numbers take time to build up to a point where a pattern of similar product issues and comments become apparent to Apple teams and the to specific, cognizant Apple teams.
So, Apple had no way to know to “step in” on this issue until it has actually become a large enough of an issue to warrant Apple’s and specific Apple team’s attention.
