Why am I missing Facebook friends from my matching list?

Missing friends from any of your social networks list in Sync.ME, may have to do with your friend's privacy settings on those social networks.

For instance: If your friend declined to give access to third party apps on Facebook then he/she will not appear in your Facebook friends list in Sync.ME.  The same is for LinkedIn and Google+:  In Sync.ME the Google+ list is limited to the circles that the user made visible to third party apps.  More info about Google+ settings for third party apps: https://support.google.com/plus/answer/2485911?hl=en

 

In addition, Facebook's new API restricts the amount of Facebook friends the app can show
