I've posted about this before and still have this issue. I cannot chat to one particular friend in an xbox party chat. e.g If i start a party and this particular friend joins then he will have a white 'X' next to his name and we cannot communicate. and if he starts the party i have the 'X' next to my name. If another friend joins the party then whoever has started the party can communicate with him but the player with the 'X' cannot talk to either player still! We both have open NAT types and have tried doing a hard restart of our system and clearing cache and also alternate MAC address but still nothing changes. This seems to have happened since the update where they added the 'X' feature to the party chat as it was completely fine before.
Any help please?????
