Same issues here, that and I am a free user. Which I should be able to listen TO MY OWN MUSIC without paying a sub to someone. I use other applications that do the same thing Spotify does.
Which is sad, I really like the design, layout of the app, as well as love their radio programing, better then most.(at least on the desktop) But not letting me listen to my own music on my phone is a burning at the stake offense. So I'm uninstalling your app today, which I really wanted to use. Your competitors give me what I require.
Hope you guys have plenty of rope to choke yourselves with. Cause you all could have been superstars, but decided to drop the ball on the populace.
Okay, so I have been struggling with this exact problem, and I fixed it by simply opening the Windows Firewall and unblocking Spotify from public and private networks. For some reason, there were two files named "spotify.exe" One was allowed on private, the other on public. I simply allowed both on both files and the files started syncing onto my phone.
I was about to switch to a different music provider for laptop and phone...
Tried deleting the cache... Almost deleted the app to reinstall.
Found this post. Changed the Windows firewall settings to allow Spotify (I also have 2 entries in the firewall settings) on domain and home networks for both files (currently on a home network, decided against allowing it on public).
Still wasn't working for local files even though downloads for "normal" Spotify songs were working.
Realize avast also has its own firewall and it was blocking Spotify. Set my network type to private on avast internet security and now mine are working as well.
Thanks for the tip in the right direction, btsheehy.
