Sync problem on Android

[Krellus]

Hey!

I have about 10-12 playlists on my Samsung Galaxy S2 that I listen to in Offline mode.

My problem is when I want to sync a changed Playlists on my laptop.

Suddenly most of my tracks aren't available on my mobile Spotify anymore. It takes 40 minutes to sync it again... It took a second to loose them all. Don't understand what is happening.

It works really well in Offline mode on the mobile until I try to add the new tracks.

Why remove all the previously sync:ed playlists?? I have definatly not authorized "it" to remove anyting.

Regards

Chris
