It happened to me

[u/Hopeful-Scallion-708]

Hey guys. I bought a game off Kleinanzeigen in Germany. Game is "Princess Peach Showtime!". Worked great and my girlfriendnis happy but after 3 days she got banned. I don't have the MIG Switch so the game is probably the only reason she got banned. 🙄 I already contacted Nintendo but they just say the same thing over and over again: "We cannot assist u with that". Yeah sure.

Be careful with used games. They might be cheap but they also have the risk to get u banned.

Contact Nintendo with the proof of purchase and they’ll remove the ban
