i have started getting joy con drift right after it installed and i already had it but switched the analog stick a while ago,do you think its my controller acting up again or the dlc that messed up my controller
I haven't experienced any drift in the Pokemon DLC (whether using a third-party controller or the joycons), so it's probably your own joycons starting to drift, at a very coincidental time.
I've noticed that joycon drift tends to be more noticeable in games than out of it. For instance, I was playing Overcooked at a friend's house and using her joycons, and I didn't even notice there was drift until we got to a water stage and I kept slipping and falling into the water. It might just be light drift that's exacerbated by the game itself.
