Help fix my problem! Facebook connection

I've got multiple King games, Candy Crush Friends being my favorite, and none of them will fully log into my account through Facebook!! My progress is saved, but it won't let me make purchases, load my characters, no daily bonuses, etc. I've gone through my Facebook account to make sure that my settings haven't changed, and it says I'm logged into my King games through Facebook. So I don't know what the issue is?!?
