I've been trying to test crossplay for a while now. Haven't had any luck with it. First I tried running the server on my Xbox dedicated server and connecting via PC, I'm not able to join it via friends list or invite. I tried it vice versa, with the PC as server and the xbox as client. Same result. In both instances I CAN send the invite, but the client doesn't receive the invite. If I access (pc) host's profile via friends list on the xbox the option to join game is greyed out. Whereas accessing same (xbox) host's profile via pc no option to join game even appears. it's worth noting all other communication varieties work (party, stream, personal messages etc). Also worth noting that the versions numbers for the xbox and pc are different. 768.1 is PC version. 768 is Xbox version. with no option anywhere to update.
