If you cannot see any game lobbies when you join the Multiplayer lobby browser, there may be a few issues:
🛠 Make sure you have enabled CROSSPLAY.
In the in-game Options menu, go to the Game Options tab and ensure that “Allow Cross-Network Play” is checked. All players attempting to join the match should check this.
🛠 Make sure you are on the latest game build.
If an update was released recently, you will need to be on the latest build to play with the rest of the community.
🛠 Make sure your local or campus firewall is not blocking connections.
Make sure the game is whitelisted so it doesn’t get blocked in the matchmaking lobby.
