Macbook Pro MAC OS high sierra and an Iphone 7
My Question or Issue
Some time ago I noticed that Spotify did not play certain local files on my Iphone anymore. I have a couple of playlists that are made available for offline use. Previously Spotify would be able to play the local files in these playlists just fine, however now it won't play certain songs anymore.

I have tried the following:
How can I fix this?
