Left joystick in the switch controller bends?

With my switch it has recently been the case that in fortnite or minecraft the character suddenly just drifts to the right or left. I don't know anything about technology and just wanted to ask

Yes, that is the joycon drift, as Nintendo had no nock, so putting in a bit of quality is a very common problem I also had. Try wd 40, there are also many tutorials.

Ah and please stop playing fortnite

Ok😂😂😂
