So me and a friend have been game sharing for awhile now with no proublems. But when I downloaded the new Xbox preview update it made the game sharing glitch out on his end. He doesn't have the new update and I do. The games I buy now don't show up in his ready to install like they used to. Yet he can still play my old games so he's still linked. Everything works fine on my end and I'm not sure how to fix this any suggestions?
