My friend purchased the Destiny Legendary Edition for the Xbox One on Saturday. I sent him a referral link yesterday and he only installed it earlier this evening. At first he made his Bungie.Net account and it said that it was linked to my account but he had to first install and play his game. He has now installed and launched the game and his badge has disappeared from my profile on Bungie.Net and he says that he is still receiving a prompt to purchase the game before he can be linked to me.
