Been playing LAN games (hosted on XBox One S, Windows 10 laptop connects) in the betas for a while. After the upgrade to 1.9.0.0, we were able to play together on the LAN one time.

Since that one play, the Windows 10 machine is unable to see the in-progress XBox game on the LAN.  When I go to the friends tab to start a game, it simply doesn't see the XBox has a game in progress like it normally does if I join while she's playing. Same accounts as before on both systems.

I've rebooted the router, it hasn't helped. Verified the XBox game setup allows LAN play. Both machines are on the same subnet. I don't think there were any Windows updates or network configuration changes since we played together once successfully. The PC has been rebooted since this problem started.
