I play on Xbox One s and my friends all play on ps4 and PS5. I can't join my PS5 friend's world when I accept his invites. I see him on my friend's list, we all have crossplay enabled and there should literally be nothing stopping up from playing. I made sure everyone had their Xbox online status set to online. I see them in my friends list and they see me. They can even join me when I host a server, but I'm on old gen so I don't want to host when PS5 would serve as a better host. (Even though when we played on my world I couldn't even hear them on voice chat at all no matter what I did.) I've tried literally every solution I could think of and I've looked at countless forums and support sites and no one seems to be having my problems and no one seems to have a fix. I need help guys this is really irritating, 3 people bought this game to play with me and we literally can't play together its extremely frustrating.
