I can't find the deluxe Version for xbox one in the Microsoft store. Why i can't pre order...

it's in the FAQ and their website there is only the digital deluxe that contains both, if you pre-order it before release, you will get all the pre-order items in April.

You'd have to ask the developers. The Series S/X digital deluxe version does also include the One version of the game.

And looking in the Xbox One Store online says that I do not own the Digital Deluxe Edition. That is the version that I pre-ordered.

All services are running and this error still occurs.

There are numerous reports of this same error.

It appears to be affecting ALL owners of the digital deluxe version of this game. Microsoft store is not recognising that they own the digital deluxe version (and therefore both x/s and the xb one edition).

The store is only recognising they own the X/S version, and not the deluxe version. Which is why the xb one version is no longer being recognised as being owned.

It appears that Microsoft appear unaware of this issue. All we see is people being asked to do the troubleshooting, which will NOT fix this problem.

It is a Microsoft DRM issue specifically with this game. I can't find anywhere that Microsoft has even acknowledged this issue yet.

Nothing has been taken away from you. If you pre-ordered the Xbox one version, you will have to re-pre-order it as the release date changed. If you ordered the deluxe version that contains the Xbox one version, you’ll have to re-pre-order it for the same reason.
