To fix your Xbox controller issue, you’ll need to do a firmware update on the controller itself. And that can only be done on windows unfortunately (unless you can figure out how to do it in a VM). Then when the firmware is updated, you install Xpadneo and you should be golden. How do I know? This is exactly what I had to do thanks to a random redditor who chimed in to help when I had this same issue. My controller now works on Bluetooth with zero issues.
