What's the point of syncing when it takes 17 seconds to load that one lyric you just synced, kind of messes up the tempo of actually syncing don't u think. And don't ask me to ask support for help, you need to help yourselves or your gonna loose your app and all the money you make from it. Telling customers with a review the same response every time is disrespectful and poor effort
