Hello. I bought a new 2023 Yukon XL Denali a month ago with the rear entertainment package. The screens were working fine until today. The touch functions stopped working. If I touch the driver side screen it controls the passenger side. The passenger side does not work at all for touch. I do have a fire stick plugged in to the HDMI 1 port and that works fine with the remote for it. I’ve reset the rear media, turned the car off and on and unplugged the fire stick and the touch functions still don’t work properly. GMC tech support could not help. Any ideas on how to remedy this issue?
