Fans of Theatrhythm: Final Bar Line on the Nintendo Switch are finding themselves unable to play the popular Switch rhythm game for an odd reason. The Final Fantasy rhythm game spinoff series has received multiple iterations since the original game debuted on the 3DS in 2012, allowing players to play along with their favorite Final Fantasy tunes. The series saw multiple releases on 3DS and recently welcomed its first console launch with last year's Theatrhythm: Final Bar Line on PS4 and Switch. Now, fans are finding themselves unable to log into the game for a curious reason.
