Yesterday it was fine but all of sudden this morning i can't use my premium account on my mobile but on my pc with the app it works ! I don't know why ,i use the same account on my pc and my phone but on my phone spotify doesn't stop to tell me to pass on the premium version even though i already have it and of course i can't play the song i want etc..
I have no problem if i use spotify on my pc so i checked my account subscription just to be sure and it confirm that i have a premium account . You will find the screenshot of my account in attachment. I am a french user so It's in french.
