Hello. I am making a multiplayer mobile game with using photon bolt and playfab.I would like to use my own server instead of playfab server. How can I do that? I have been searching this for days but I couldn't find anything useful. Links like https://docs.microsoft.com/en-us/gaming/playfab/features/multiplayer/servers/custom-game-servers are broken. I know there is settings for external servers but what to do next after activating "Use external game server provider" settings.
