So I have a Moto G 3rd generation android phone running on lollipop. For some odd reason, recently, my spotify randomly deletes all my offline playlists without my permission. My offline playlists are saved on my SD card so I have to resync them every time this happens which is about 10GB worth of songs. However, spotify shows that this 10 GB is downloaded and occupied. It's just that I can't see it downloaded on my spotify app.

Once I delete and reinstall the app, the SD card shows that its not functioning properly anymore and has to be formatted. This is followed by a format, resync of all my playlists. This has happened to me almost 5 times now after every 2 to 3 days. Any solution for this?

THANKS I REALLY NEED THIS!
