Review on Wireless Pro Controller for Nintendo Switch Lite - YCZHDV Switch Controllers with NFC, Wake Up & Double Vibration (Black) by Michael Luna

I followed the instructions to charge and turn on the controller. My friends and I played Mario Kart where I tried to use my items with 'L' and drive with 'R'. None of the buttons did anything. In System Preferences, there is an option to "Scan Input Devices" that shows what keys you're pressing. Tried "A", "B", "Y" and "X", everything worked. I lowered the sticks and pressed the direction button (D-Pad), they worked. I pressed 'L', 'R', 'ZL' and 'ZR' and none of those 4 keys showed as pressed and they didn't work at all. I even tried a few games and they never worked.
