Also, did you install switch films by chance?

How hard are you having to press to install these switches on the PCB? I imagine if the PCB is pressing on the switch housing hard enough to deform it and interfere with the keystroke, then it must be absurdly difficult to install in the first place.

Any pictures you can share? Can you maybe install a switch without the top housing to observe what’s happening inside?

I have the Ultimate Bluetooth Controller from them and it’s been plug & play on everything I’ve tried. Fedora with KDE picks it up on 2.4GHz mode just fine (and Steam recognizes it too). My iOS devices recognize it as a Nintendo Switch Pro controller when using Bluetooth mode.
