I've got a problem where not all my Facebook friends are available for me to link to contacts. if that makes sense. I click the broken chain in the corner of the contact card, select Facebook , then there's some that are missing. Only noticed this because my girlfriend used to be linked but now isn't, and I cant find her, plus all the others that were linked before and aren't now. I removed my Facebook account and cleared all Facebook cache and data, re logged in and still got same problem.
