ok so i'm playing an open-world adventure on my Switch 2 and teh older left Joy-Con has started drifting. menus scroll on their own, and in-game my character slowly wanders off. i ran a stick test with my hands off and it's clearly not centred:

Controller test
Release both sticks. Both dots should rest in the centre.
Left stick X 0.18 Y -0.26
Right stick X 0.00 Y 0.01
ive had these controllers for a while, but Im careful with them. is calibration enough, or is this the infamous drift everyone talks about?
id realy rather not keep buying new controllers, if theres something that actually lasts, Im all ears.
