FB Friends recovery on new iPhone
What is step by step process to get all friends in my FB app onto my new iPone (just got yesterday), that were on my old iPhone? Logged into FB on new phone, and shows no friends or old info, without going back and asking them to be friends again.
This question pertains to helping a friend with a new iPhone, & had an older iPhone that was traded in. Not any of the devices listed below.
iPad, iOS 9
