I have two questions around this topic.
First of all: How can I show only the mutual friends two users might have?
I tried pulling the Facebook friends IDs into the “current user” as a text and then checking against each other, but that doesn’t really seem to work.
Which leads me to my second question: Do I even need to pull data from the Facebook profiles and store it as an extra data field under my users? (Name, Password, Email, … , Facebook friends?)
