If you usually play on Nintendo Switch another platform(s) and happened to update your game on your secondary platform(s), you will temporarily be unable to launch the game on Nintendo Switch.
However, you can still play on the other platform(s) in the meantime.

Our developers team is investigating the issue, but in the interim, we advise anyone who plays on Nintendo Switch as their primary platform not to update the game on a secondary platform until this issue is resolved.

We sincerely apologize for the inconveniences!
