Awesome app but please help…. – GarageBand Review

It’s a pretty good app simple enough to use and great for beginners I have made multiple tracks using this but I keep running into one issue and although I tried to ignore it as best possible it has driven me insane. Parts of my tracks are just completely disappearing. I am very careful to save my work that’s for sure. It has even happened while in in the app. I work on one instrument then move to work on another and when I go back to that instrument the recording is absolutely gone. I’ve had to redo a whole piano part twice when I was excited because I thought I had finally finished. Please help I don’t know why this is happening.
