After 1 year of use, the left side of the controller stopped working. I solved it by changing the sides of the ribbon, and that worked for a while. Now the left side stopped working again, with no possible solution. I don't know what to do because the right side of the controller works with both sides of the ribbon, but the left side does not. It is incredible how such an expensive controller has so little support or upgrades to adapt to the games and not the other way around.
