I bought today from toys r us, a nintendo switch. I went home and plugged it in the wall and it worked fine and it charged. I set up the dock and connected it with the hdmi and ac adaptor. When I came back from like 3-4 hours later, I tried to dock it and the dock light started to flicker and it didnt want to charge the switch. I disconnected the switch and the ac adaptor and tried to connect it directly, but it didnt charge. After I disconnected everything and waited like 20 minutes, I connected everything again but the problem was still there. So I got stressed and started to slowly wiggle the switch in the dock to check if i connected it correctly and started taking out and in for like 6 seconds. After that, the light stayed lit and it charged the switch. A few minutes passed and i tried to charge it in handheld mode without the dock, and it worked fine. But im worried about the cable or my switch charging port breaking in the future.
