I have my Switch for 6 Months and my left Joy-Con has a problem. He works perfectly fine but the left Joy-Con is missing a tiny plastic thing (In the picture). Because of that the Left joy-con dosent stuck in the Switch and can get removed without pushing the black button on the back side easily. Its really annoying and i cant remeber that i break it. I was everytime very carefull with the switch. Is it a Factory misstake or is it my fault? Can i return it to get a new left Joycon?
