Good Evening, First off I apologize if this is the wrong board to be posting this. I am new to this site and I am looking for answers that I cannot find anywhere. Here are my issues. First issue. I am unable to play cross play/play anywhere with my friends and family. I am trying to play on my PC and have my friends and family join my game, or trying to join their games to get this to work. I can't invite them to my game and they can't join mine and visa versa. Is this feature still broken or is there something that I am overlooking in getting this to work? Second issue. Do I have to create a new gamer tag to use that to post a dedicated server on my PC in order for me to play on my xbox one x? I have a very powerful gaming PC that can play the game at max settings and I want to use it to run the game work so me and my friends and family can play on our Xbox's. I deeply appreciate any clear and precise answers to my questions. Thank you very much for your time and understanding.
