I have a lot of multitrack songs that I've created, and it was working great for months. Suddenly it's stopped playing back some of the tracks (tracks 2 and 5). Nothing is muted, and all tracks are active in the routing panel.
All tracks are on my device.
I tried to re-link the files, but that crashed the app. When I restarted the app, the file was missing from the folder! I redownloaded the file, relinked it, then it played fine. But then I played another song, and the bass track didn't work. Then I went back to the song I just fixed, and now it doesn't work, either.
I've lost several track files this way.
Please advise.
