I used the preview version on my desire hd and it worked great. I then upgraded to the final release and started getting problems. The app seems to go onlineand offline at will and songs stop playing at random. Even the downloaded songs and even if the app is set to offline mode. I didn't bother to fix it sinceI bought the galaxy s3, but the problems appear on the new phone as well. I did the following:
Installed the new app from google play store.
Logged in with spotify username and password. I tried facebook as well.
I downloaded a playlist in high quality.
I played it. The song stops after a short while at random.

Any solution?
