Good morning,
My son received an invitation, in his Halowaypiont account, to join the Spartan Company where I am.
The problem is that he does not read the messages and therefore can not accept the invitation and enter, I think because he is a minor, even though I as a father have consented to the permissions on XBOX for use at HALO game.
I ask you how can I let him in?
I don’t believe there is a permission level that can solve this I’m afraid OP. Spartan Companies rely on the Inbox feature of Waypoint to receive the invite messages, which is not available to child accounts for privacy / data protection reasons.
