Hello there,
I have a player complaining he lost he's account connected to facebook, playfab returns an account not found and my game them prompt him to create a new one, I was able to find his "lost" account by using he's Facebook name wich does not guarantee ownership as ppl can have the same name on Facebook, so how should I confim he's account and track why he's not being able to log in? I know that if you go to (Facebook > Settings > Apps and Websites > Target App) you will find your user id for the game, but I can't find any way of checking it on Playfab side.
