My Spotlight Song progress seems off!
There are a few potential reasons for this.
If you play harmonies, you will get a score on the leaderboards, but it will not factor into Spotlight Songs. If you play Pro Drums, the scoring will be adjusted to be on par with standard Drum scoring.
If you played a song offline, the score will not upload to any leaderboard when connecting to the internet later. Make sure to play songs while online if you would like scores recorded!
