Hi all I've just bought the Xbox One and newly installed Halo. Automatic updates are enabled, so I presume patches have already been downloaded. I am able to play friends in custom games, but matchmaking entirely fails. It searches, claims to have found friends, and after a few minutes indicates it cannot connect. Xbox network diagnostics indicate that my connection is fine, and I play online over PC so I doubt it's a restrictive setting. Is there anything I can do or any way I can doublecheck whether the updates have been downloaded as expected? (Should the updates have been downloaded as part of the game installation process?) Thanks in advance
