I am using Spotify Premium on an HTC Desire S. My problm relates to off-line mode. When i force Spotify into offline mode it will only stay offline providing the phone remains switched on. If i turn the phone off and back on when i try to login to spotify a pop up will appear to say 'another user has forced spotify into off-line mode'. If i don't have internet access it then won't allow me to login. This is a real pain when away on holiday and the app never used to do this.
