HELP- Spotify Playlist does not work in iPhone anymore

[FedoCoke]

Hi all,

When I became a spotify user/client, I created two playlists which include Spotify songs and some downloaded iTunes songs (in my iMac). I played those two playlists without any issues for several months, but the other day it stopped playing properly in my iPhone. Now it only plays the Spotify songs in the iPhone Spotify App. In my Spotify App in the iMac, it still plays all the songs.

Please help to solve the problem. Thanks!
