so i got a new pro controller out of the box and the left stick would get stuck when i moved it down and i tried rubbing alcohol and all that stuff until i got frustrated and just started twisting the stick and it fixed the issue… yknow how if you pull on it the stick it raises up a bit? yeah i twisted it clockwise and when i clicked it back into place it rotated back to its normal postition and the resistance was way lower and it wouldnt get stuck so i twisted it counter clockwise and when it clicked back in place there was almost no resistance and it flicks back to neutral position now hope that helps (obviously dont twist it too hard. try like 90 degrees to the left or right) hope this helps
