We are currently investigating an issue when joining Deathmatch lobbies where players will not be able to fully ready up, and therefore the game never starts. In the meantime, please select either "Team Deathmatch", "Form Ball" or either of these two modes in a Custom game as they don't appear to be affected by this same issue.
Thanks for your patience as we get this resolved!
