Why won’t my Nintendo Switch charge ANY controllers on the left? (It’s not a problem with the controllers)My switch is also 3 years old if that helps.(Also the left side is really wobbling)

@oliviaspromblem this “the left side is really wobbling” could be caused by a bad rail. I would replace it and see if that fixes the issue. Nintendo Switch Left Joy Con Sensor Rail Replacement Nintendo Switch Left Joy-Con Sensor Rail
