Party Invite Bugged, Won’t Join Party

I did both of those options but it still won’t let me join a party. It takes me directly to the profile page of the person inviting me when I click on the invite but from their profile page I still can not join the party.

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.

Join the party! No seriously, we're actually making a party and you're invited.

Have one player start the game then invite the other person to a party. Once you have invited your friend to a party you will have an option in the pause menu to invite party to game, so once they join pause the game and there will be an option to simply
invite party to game.

Same here, cant join party or invite party!
