Violin student

We purchased this app to use with my daughters Suzuki violin practicing. Slowing down the music is really helpful when she is learning a piece and needing to get notes in tune. However, almost every time we use this app, we get an error message when loading songs to use. We have to end out of the app, reload music and it takes up a lot of valuable time just to get this app to work. Very disappointed because we had high hopes for this application.
