2021 Model 3 LR - Screen glitched out while driving so I performed a soft reboot at my next stop. Ever since, only buttons on the bottom bar and left side of the screen are working. Everything from the Nav side over is unresponsive. Performed several soft reboots but no change. Wanted to power cycle off the vehicle but that button is unresponsive and can't be done. Service appointment scheduled for next week. Spoke to a tech over the phone and he implied it may be mechanical. Anyone else experience this?
