Since the update, I have been unable to matchmake for a PC only game in any game mode.
Initially I had the issue of being kicked from a session because it couldn't connect properly to a console player a few hours ago, which resulted in a matchmaking penalty as I was "leaving the session". This occurred several times in a row so I decided to try to play without the setting to see if that would resolve this, however if I disable the crossplay option I have been entirely unable to get into a single game for several hours.
I have reset the router, rebooted both Uplay and the title, rebooted the PC, checked the NAT type (which is green) and still cannot even get into a match at all in either PvE or PvP. I have tried matchmaking with Crossplay since and gotten into games however these lobbies had gameplay issues that caused people to fall through the map and latency issues as have already been reported by others, but I still cannot get a single game without the crossplay option enabled as each attempt I make the timer runs endlessly without finding a match.
