My Question or Issue

 Had some Playlist and albums downloaded.

Downloaded the perry rhodan silver editions as far as possible. Heard the downloaded and deleted afterwards.

Wanted to download a remaining book. 

Couldn't cause limit reached.

Deleted all music from Spotify, not working. 

Deinstalled Spotify completely. Could download 2 playlists with about 400 songs, have no albums or single songs downloaded. Can't download any book bc limit reached.

Logg off and log in again does not solve the problem.
