@Zacor omg I'm having this EXACT issue I thought I was alone! I have exhausted the privacy options in both my xbox live account and the game itself... nothing seems to help!
Converse with fellow players
Hi! my roommate and I can't seem to invite each other. We can send invites, but nether of us get a notification that we received an invite. We thought this might be a LAN issue, but when we asked a third friend to invite us both, he could invite my roommate, but I didn't get any notifications. I think this is something on my end but I have no clue what it is. Is there a client order I need to complete? I don't have any privacy settings or "decline party invitations" on. Is there some other setting I'm unaware of that would cause this? My xbox live account is new so I've never muted anyone or blacklisted anyone. Thanks in advance for any advice!
