Since the launch of Windows 10 beta version we have been successfully playing on Multiplayer LAN with all of our 5 PC's running the same versions, all on the same local network, however we have just tried to join the LAN multiplayer and the game does not show up in any of the players friends list, except the host.

We have all confirmed that we are friends on Xbox.com, we have all checked that when hosting a LAN game that the Local Server Multiplayer is on, but we are totally unable to see hosted games from anyone on the LAN.
