I love the idea of this app, however, it seems to have quite some bugs. The lessons have issues (like it’s asking question whether it’s properly sync, but you cannot see any lyrics in the video/question, there’s no way to answer it). And when I try to contribute to sync a song (using either iPhone/iPad), it just pops up error saying “We are Unable to perform this action. Player unavailable”. I’d love using this app if these issues are fixed.
