Spotify songs not available on Djay for ipad/iphone?

I have spotify premium and i found that a few songs i am able to play on spotify are not available in Djay. Specifically, a song i was mixing on Djay via spotify premium 2 days ago became unavailable just today, with the message that it is not available in my country. However, i could still play it on spotify.

Hi there,

Thank you very much for your patience.

Best regards,
