maybe you already know this..... the household gameshare agreement requires you to designate (1) unit as the "Home" unit, everyone can play all games on this unit only. You as the license holder/paying customer, are the only one who can play/sign in on unit number 2. I have 2 XB1's and this is how it works for us. We both signed on this morning at the same time and all content is there and available for each unit.
