Invites and group posts

I can join parties and receive party invites just fine. The problem is the game invites. For example, I was trying to play Call of Duty: Warzone through a Looking For Group post. I join the party but then don't receive the game invite and can't invite
them to my game.

Hi there Will! Christopher here, an Xbox fan and been on Xbox for years already. I would really love to make your day by helping you out. Let's try the following!

Open the Xbox Guide by pressing the guide button on the controller and select

Settings.

Select Network Settings.

Select Advanced Settings.

Under Change Settings select Alternate MAC Address.

Select Clear.

Sometime when I play people tend to invite me to parties and chat groups when they find the way I play and sometime I use the same thing but I suggest as well like other post use Discord, the forums and the group on xbox live, is good way to know people
and invite the to play

Not allowed to invite gamers to a gaming discord, to game? And have in game competitions and giveaways? You definitely need to Contact someone then, because that's 70% of all group posts.

It is an issue for everybody at the moment.
