So this has happened a couple times. And what happens is that spotify forgets my account and I have to log in again. It also forgets where my storage location is in the settings. When I try to set it back to the area it was, it says there's an error. Then when I restart the app, it's set to the location I selected, But with none of my music there.

I don't know if it's by chance it happens, but it seems to only occur when I turn off my device with the app on. This has been very aggravating. Because during a drive, my tablet lost all of my downloaded playlists when I turned it off like I said before. Very annoying. Spotify, please fix this.
