Spotify premium bug on iPhone 5

[Timpster]

I have functioning Spotify premium for my account, and I have 0 commercials and I can select any song I want. However, I cannot rewind/fastforward on the bar for the song duration, I cannot shuffle and I only get 5 skips of a certain song before it tells me:

"You've discovered a premium feature - start your free Spotify premium test period to unlock it."

All of these are things that occured when I did not, in fact, have premium. I got it a couple of days ago, I have tried logging in and out of my account, restarting my device and restarting Spotify; nothing works. Is this a bug and if so, please fix it. It gets annoying when I cannot skip ahead in songs or when I need to constantly unlock my phone and manually select new songs to play instead of just hitting "next".
