Gifted a game to a friend, he accepted it, but it does not allow him to download the game.

Hi Michelle, that's not usual. Can you get your friend to take a look in his hidden games in his library. Is it possible he tried a demo of the game and hid the icon and forgot. I say that because I did the same thing when I thought Red Matter 2 which I bought had disappeared! 😁 On the library, he just needs to hit the games menu at the side and open hidden apps just in case it's there.
