I was using this service while free and then after the trial expired I paid for the premium subscription. But now I can no longer play a band by name (voice or type search). I can also not add a favorite band/radio from a search. I think this is because I'm not properly signed into Tesla's slacker account. But I can play the standard stations offered up by the interface. So I'm paying for a premium feature but unable to play anything other than Tesla preset stations. Ideas?
