Likewise. Since the recent engine update, the Game Worlds menu is there, but no lobbies appear for any games. I can join through a friend or can make my own, but cannot see in-progress games.
For some reason, the desktop computer in my house (I play off of my own PC) has game servers showing up, despite the only difference being a hard connection vs WIFI. I re-installed the game on my pc and the issue is still present.
Also worth mentioning is that condo servers off the main menu are also not there in addition to the previously mentioned game servers.
