Context: This occurs in crossplay between Steam (PC) and Playstation 5 (physical console). There's currently a bug where I cannot see my friends if they are online and in the same server as I am. ...

I also am experiencing this, solely with crossplay. If I'm in a party with my friends who are all on PC, no problem we can all see each other. As soon as my friend with PlayStation joins, no one can see each other. Sometimes they'll pop back in sight for a couple of seconds before disappearing again. Really sucks to see it wasn't in the "known issues" .
