I'm not sure if the devs are aware of this but, it's been 4 days since the game releases on Switch. and since then me and my buddies are having a hard time playing for 3 days now, showing the same message "Login Failed. Check info" all over again. I hope the devs can do something about this issue.
Edit: after playing for a day without having the problem as before (Login failed. check info) I think this issue has been fixed! THANKS DE!
