sorry if this has already been asked and answered but i spent two hours looking for an answer before creating this post.
my wife and just got the game yesterday. we are playing co-opbut we are unable to figure out how to invite a person into a clan. we have created a clan, but cant figure out hot to send an invite.
It’s not very intuitive on Xbox – you have to stand in front of the person you want to invite and hold X to interact. Then the wheel menu pops up and one of the options should be to invite.
edit - you also have to be ‘ranked’ high enough in your clan to do it – I think the two bars rank allows it, but not the single bar.
