Spotify keeps deleting downloaded playlists.

[mxdirector]

I would say this issue has occurred twice since I resubscribed to spotify a month ago, under two completely different circumstances.  one involving travel so I was left musicless when I needed it most. The other time being today 

So i look at my phone today, and click on playlists and it says "nothing to see here". I check in the app data how much memory spotify is using, it says 5gb, so it hasnt deleted the files (misleading title). so the files are there spotify just dosnt recognise them as downloaded. So i have to redownload all these playlists.

The funny thing is, this is an issue that I see popping up alot, since 2012 no less. What the hell is this issue? how the hell do I stop it from happening? And if it happens again, will I be compensated?
