Playlists partially resync every time i open spotify

[myroundbox]

Lately i've been loading spotify in the morning and the end few tracks (up to about 10/15 maybe) of playlists decide they aren't synced and download again. This has been happening every time for the past few weeks. 

I thought it might be to do with not having much space left but i have also tried removing some playlists to make space. It's not too useful as now my 3g data has ran out. Anyone experienced this problem/have a solution?

I also activated spotify on an iPhone, wondering if there is a device limit issue perhaps?

Thanks

I have the same problem (on samsung s2 android 4.1.2).

The application tells me that I ran out on space, but I have more than 4Go.

I also need to reconnect my account each time the applicaiton is closed.

This is on a HTC One S for me.
