I literally have the same problem right now. I panicked last night, non of the right buttons work except the joystick. I’ve updated my joycons, my whole Nintendo, but they still don’t work. Someone said on a different website to leave it be for a while or couple of days so I’m gonna wait. It’s crazy that we all have the same problem and it’s the RIGHT joy con as well. I’m wondering what causes it:/ you both made me less worried, I’ve been looking for answers and solutions everywhere and I couldn’t find anything
