Same issue here with our iPad Air we just bought in April. We have an open ticket with Apple. After sending it in for a repair, they changed their tune to say it's an OS issue and they are working on a fix. I would encourage EVERYONE to log a ticket with them to put the pressure onI have an iPad Air 3 and since I updated to 13.4 my screen will be unresponsive to touch in random spots. Is this a coincidence or is there an issue in 13.4?
