Anybody got one of this GC adapters? Got this one from AliExpress but the Switch isn't recognizing the controller, no luck with the PC either. It has a USB A port on the back, is that necessary even though I'm only using 1 controller?

Some people have suggested to me that the problem may not be only about the screen protector itself, but a bad stylus. Is the tip supposed to be made of a different material from the body?
