Whenever I complete a game in SC2, I can either click Play Again or go looking for another game. If I click on anything to join a new game, I get stuck in “Entering Lobby,” and I then have to exit out of SC2, restart the blizzard agent, and then start over from scratch.
This has made group play impossible. I’ve also found this has been affecting many people I play with, too, not just me. I’ve had this issue for 5+ years now on 3 different computers.
