From a week until now, my spotify stoped to sync local files from my PC. It was working just fine, until I deleted my playlist and wiped the cache.
I tried the firewall solution, creating new playlists, uninstall the app from android and from PC, but nothing worked.
I am using an ASUS Zenfone 2 with android 5.0, with Spotify 126.96.36.1990
This is a very commom problem, and It seems that Spotify doesn't care to solve.
