Was happy to finally get the latest update so private matches are enabled but have one problem. When two of my friends join me in the private lobby and I select map and game mode the "Start match" selection is greyed out. Can't start the match whatsoever. In the upper right hand corner is the "waiting for players " indicator and it just sits and spins even though indicating 3/6 . I thought you could play with less then six players for a private match ? My friends are experiencing the same issue when they invite me (or anyone else) to a private match.
Is there something else that is required ? Do we need to have finished the campaign ? I'm at a loss here and would love to just get a private match going with my friends.
Any help would be appreciated.
