"I am using Unity. Do you have a sample of a Unity-based game interfacing with the game server SDK? We do not have a Unity sample demonstrating PlayFab Multiplayer Servers, but should have one by January 2019. A small group of preview customers have gotten the C# GSDK to work with their Unity-based game server but it is not a straightforward experience."
Is there any update on this?
