Missing certain music sheet – Medly Review

I still love this app with the amount of updates you guys do every month. But I have just one issue. Whenever I try to save my music and exit the app, the next day when I return, there’s blocks of music that I find missing and that I have to start ALL over again from scratch in order to make up the lost audio. Is this a bug? If so please fix it. I’m tired of having to redo everything over and over again whenever my certain progress is lost.
