Local files will NOT play on my Android phone

[CaptainKiwi]

I can't get my local files to play on my android phone. Any song that is linked to a local file will not play on my phone, even if I use the spotify file (and unlink it from the local file on my computer).

Some of the songs will play if I'm connected to the internet, but then what's the point of offline mode? I'm a premium user, and the failure of this basic function is really annoying. I've already cancelled my subscription for next month and won't be coming back if this isn't fixed soon.

What exactly happens when you synch a playlist of local files following these instructions? Do you get any error messages? What device, android version, spotify version?
