Cant join or invite

I have a issue inviting my girlfriend and she cant invite me. I can join other players on the game. Is this a issue with us being on the same network

If you guys have each other muted then it automatically adds you to the other's blacklist in-game. It is a known issue.

yeah, if you are both muted on your XBOX systems, that is the problem. Unmute and there won't be an issue.

@AndrlCh thank you so much that worked she had me muted.
