On release you couldn't add friends across PS5 and PC if the PC player's steam name was anything other than 3-16 alphanumeric characters (like a PSN name). My name had a special character in it so when I friend my bf he gets the request, but clicking accept doesn't do anything. So I changed my steam name to one that should work, but it doesn't update on the back end so my friend requests still have my old unfriendable name. Following the bug reports on discord, it looks like the mech update broke it for some more people even.

It's frustrating because it has sort of worked for other people. My bf has one friend on steam. We've been waiting for her to get online to see if she can be a hinge to get us in a game together, but I guess it's finals or something.

It's my weekend now so I'll add you both. I'm a little soured on The Community right now and the new update didn't fix the problem.
