moi left joycon thumdstick drift. try air spray but still the same. moi just got pro controller to play smash Bro

If base on hours of game play shows on switch, my left joycon stick clocks more than 200 hours of play. So I wouldn't say the quality is bad. Just wear and tear. But the stick feel fragile compared to my vita. As for pro controller, I just start using. For it steep price compared to ps and one controller.

For Super smash bros, I bought pro to play.
For Zelda, with my drift thumb stick, I struggle with the shrine challenge, always fall. Same for super Mario odyssey
