I'm making a game where I use photon and playfab. I was just wondering what the best method is to sign in through facebook AND authenticate the photon player session. Photon offers auth through facebook and so does playfab, but im unsure of which order to go in or which one to use. The "Sign in with Photon" tutorial has me set my Photon Auth mode to custom, but the "Sign in through Facebook" tutorial has no relation to photon at all. Whats the best way to authenticate my Photon player while also being able to get facebook friends, etc. Thanks!
