It’s a really big issue all four of my joycons went back to Nintendo a month ago due to drift of the analogue sticks Nintendo replaced two and repaired two. They just made it back before Xmas after having them 3-4 weeks! After a week two are already drifting again!
Its a major issue and if I’d know I would have bought my kids another console! In talks again with Nintendo now to try and get a PROPER solution!
