I mentioned it was fixed, but it was only fixed for the last two weeks of season 1. Season 2 brought this bug back and it's much worse than it was.
Crossplay on or off, all of us are Xbox Series X, NATs are open, Xbox Crossplay setting is open for all of us as we play PC guys in other games no problem.
Now even playing alone you sometimes (50% of the time) don't load into a game, your character stands up and that's it, this can be the first game of the day or during extended sessions. I am down to one friend only left playing this game because of this!!! Come on guys, and gals, you fixed it once, please fix it again.
Here is another post with more info
