Title says it all... What is the point of friends. It seems like anything worth doing with friends needs some sort of "instant" callback so the you can send or receive something.
Friends lists are a great feature for improving your players' ability to socialize. They're easy to work with, and can make leaderboards more engaging for your users. Currently, playfab friends only provide some basic functions such as one-way adding friends and viewing friend leaderboards. For richer functions between friends(chat, matchmaking game), you need to implement them or integrate third-party services such as photon by yourself.
