PS4/PS5/PC all hosted worlds on LAN without issue. Since updating to 1.19.63 hosted worlds are not visible under the friends tab anymore and so we are unable to play together.
Also experiencing multiplayer issues on LAN. Been playing for months with no issues. But since the update the local games are not found. PC/PS4/PS5 all used to connect with no issues.
@Mega_Spud - Only tested on LAN (all running 1.19.63) and found:
PS4 to PS5 - Joinable friends works as expected
PS5 to PS4 - Joinable friends works as expected
PC to PS4/PS5 - No joinable friends
PS4/PS5 to PC - No joinable friends
So for us it seems like it's only cross-play that's broken. We don't use the online multiplayer function so can't add info here. Hope this is helpful.
