I downloaded the Spotify app onto my iPhone and got a free 48-hour trial for Spotify Premium. After the trial was over, I decided to buy it because I love it!! So, I installed Spotify onto my computer and bought the Premium version. I'm on the 30-day free trial on my computer now, but I do have a credit card on file. Spotify Premium works perfecly well on my computer, yet the app on my iPhone will not allow me to stream on demand; it says I need to have a Premium account which I do. I logged in and out of my account and tried to connect them over wifi but nothing is working. I use my Facebook to log in to my account, does that matter? Please help!!
