Something odd with friends list

You can delete friends by opening their profile from your "friends" list and then selecting " delete friend" or "remove friend" can't rmbr which one it is, but u can't miss it.

I'm having lots of trouble adding friends, similar problem as the original post, states some friends don't have the game, weird because they don't show up on my list!! I also cannot add any friends and I'm not at my limit...lost snakes/eggs, crashing... On iPhone 5 not cool!!'
