If you're not able to play your digital version of Batman: Arkham Knight on Xbox One, you're not alone. Owners of the digital version of the game are getting the error message "sorry, we can't launch this right now. Thanks for your patience," when trying to play the game. This might be related to Batman: Arkham Knight standard edition being removed from the Xbox Store, but that's not confirmed.
Even though the standard version is missing, the Premium Edition is still listed for $89.99, $53.99 if you're logged into your Xbox Live account.
Batman: Arkham Knight has been tumultuous for PC users since its launch, even being removed from Steam and having refunds given out, but console versions didn't have the problems that PC had. The PC version later got re-released, but even that version had problems.
