Xbox Series X: Missing downward compatible games available again

Backwards Compatibility on Xbox is over...for now
For the 20th birthday of Xbox, over 70 other Xbox 360 and original Xbox games were added to the downward compatibility in November. Some players missed however some titles from the list that they had already owned, but they were not displayed under “My Games & Apps”. Among them were games like Cloning Clyde and Binary Domain. The problem with these downward-compatible games has now been finally fixed over the backend of the service. The twittered Eden Marie, Engineering Lead at Xbox. So, looks in your play library to see if there are previously missing games there.
