Some FB friends don't show up on my scoreboard & we can't send/receive lives. Why?

Some of my friends have begun playing Candy Crush Jelly Saga on Face Book.  They do not show up on score boards and we are not able to send lives to each other.

I haven't played it on Facebook yet. Is there no search for friends option? Maybe it's the same as regular Candy where this isn't an option.
