I use spotify premium together with another person. 3 days ago, Spotify started to delete all playlists and offline music I had(the other user lost his music and the playlists too). So I went on the Spotify page and used the playlist recover function. This worked fine, but at the next day i opened Spotify and turned offline mode off and suddenly all playlists were deleted, again.
We have just two 'offline devices', so the 3 device limit shouldn't be the reason for problem.
Would be nice if anyone can help me
