The Xbox One’s new dashboard has a great feature for Xbox One X owners: It lets users filter their game library to show titles that have been updated with enhancements for the new console, like 4K resolution. But at the moment, a few days before the system’s public launch, the filter isn’t working properly.

Microsoft introduced new sorting and filtering options for the Xbox One’s My Games & Apps screen in last month’s system update. Xbox One X owners have the ability to hide all games without “Xbox One X Enhanced” updates, which is a very handy option. Microsoft generally does a much better job in the area of transparency than Sony does with the PlayStation 4 Pro, and this is just one element of that.
