Game Invites Not Working Properly

In our 32-man CFM league, for the last week or so, maybe a little longer, invites to games have not been working how they used to. We used to be able to invite someone to the game lobby, wait for our opponent to go and accept the invite, and then join the lobby and begin the game. But recently, accepting the invite does not allow for the opponent to join the lobby before the game. We found a workaround that has been working, both opponents need to press "play game" at the same time and both teams/users will join into a game lobby at about the same time, and that has worked most of the time, but it is still not how it used to be or how it should be.

I'm not sure if this is the "new" way that game invites within CFM are meant to be handled, or if it is some type of bug or something along those lines. We should be able to go into the game lobby and then invite our opponent by gamer tag and/or we should be able to accept a game invite and automatically enter the game lobby with our opponent. Timing up sending the invite at the same exact time is not difficult in most scenarios, but it also should not be necessary to do so every single time.

Hope it is an easy fix!
