Hi,

I have Endless Space 2 on the Xbox (for Windows) app, along with all the DLC available there. However, it has not received updates since V1.5.26. I can see the Steam version has new content, like Dark Matter and Re-Awakening, that the Xbox version doesn't.

There is also a bug on the Xbox version meaning that DLC keeps deactivating at game launch, even when owned, and cannot be activated without relaunching the game a few times.
