Offline Playlists not downloading properly (BlackBerry 9900)

[Z10]

Hey there,

my 9900 won't download Spotify playlists for offline listening anymore. Also it has been buggy since forever, I can't get it to download more than one or two playlists anymore. At some point it just stops synching: shows 1/234 song downloaded all the time.

Already tried this
- reload playlists
- disconnect from Spotify
- reinstall the app from BBW
- delete the spotify folders from the phone

Is there anything else I can do? Does offline listening on your 9900 work for you guys?

Thanks for all kind of input!
