I can't log in on spotify

I can’t log in to spotify on my ipad air 2. the djay 2 app says that I haven’t a premium account even when I make a new Spotify account for the 1 week trail

Please double check if your Spotify Premium account trial is activated and not expired, yet.

FYI: There’s a 30 days trial for djay users. Get it here:
