I am using Spotify 0.9.0.129.g6978da9c and my OS is Mac OSX (10.6.8).
I tried lots of stuff (many clean reinstall, removing the app from Facebook in case there was a problem with some of the app authorizations, etc.), and my friends still do not show up on Spotify. I have the "There are no more people to show at this time" message.
Oddly i can see my facebook friends in the app if i try to share a track with them.
I have the same problem here, the very first day i logged in with my facebook account didnt show my facebook friends, i made a post here with my problem and you were not able to solve it, so i canceled my account and created a new one to solve it. Can you help me now? Or should i continue reopenning a new account?
