Good Afternoon,
I bought, downloaded, and installed BG3 through GoG. Booted it up and at some point, decided to look into doing multiplayer. However, I see 0 lobbies presented. GoG support has officially posted in their forums, claiming that cross-play between Steam and GoG BG3 works. I've even created a Larian account and linked it to my GoG in case that was the issue (which didn't) and even turned off my VPN in case it was a potential IP address issue that is being blocked (this idea came from the fact that Larian Forums will block accounts that have IP addresses associated with VPNs.
I've even created a lobby myself and waited for about 45 minutes before calling it. Does BG3 multiplayer work? If so, is it cross-platform compatible?
