I've had local files synced for a long time, but today all tracks appeared as greyed out. I reinstalled the app and now when I press the offline switch nothing happens and the tracks remain greyed out. I've tried everything I have found on this forum: I am connected to the same wi-fi network (which has worked before so there is no problem there), I have about 7gb storage free on my iphone, I have tried reinstalling (several times) both spotify on my iphone and on my mac, I haven't updated the spotify client since this last worked (I went back to version 0.9.15.27 a while ago which did work for local sync). This is probably the most important feature for me so if this isn't getting fixed I will have to end my subscription.
Solved! Go to Solution.
Check Windows firewall or if you have a anti-virus suite running that includeds a firewall, make sure to allow spotify.exe through. Under Windows Firewall there are two spotify.exe apps listed, one is checked for public networks and one for private networks. Put a check mark next to them both and click OK at the bottom.
Your local files should start syncing now.
