Quick Update - So I spoke with a Steam/Valve representative and pressing the Power Button in the Minus button at the same time, it reboots your system. It works after you do that. I believe something must have happened when I updated the firmware. You as the customer, must reboot your steam deck every time you update the firmware.
Valve sucks man they did nothing for me 2 months into supposed 1 year warranty glitchy screen sticks inaccurate painfully slow downloads and serious compatibility issues absolutely atrocious 💯 sorry for your experience mate
