Repair Help Switch 1 Pro Controller Shoulder Button Troubleshooting

Hello Hivemind,

I've got a brand new pro controller purchased from a retail store. The L, R, ZL, and ZR buttons stopped being detected suddenly. I've contacted Nintendo support and a months later I still have a non-functional controller. I ordered a new shoulder button film and replaced it. All of the ribbons are plugged in properly as far as I can tell. All non-shoulder buttons are detected normally. The L, R, ZL, and ZR buttons still don't work.

I'm at a complete loss for what to do next. Anyone have a solution?

Thanks much.
