Did you send them a screenshot of their website as proof? Maybe that can help. But no idea how Microsoft handles issues like that. In my region the website description is correct so I can’t really reproduce the issue myself.
They have only recently (since middle of December) added the description to the site - possibly from people who have bought the game for themselves. The 'Playable on' section still shows Xbox One though...
Not sure who to blame (I doubt CDPR is able to "edit" the game description on stores^^), but I don't see any reason for MS to refuse a refund if the account who bought the game is linked to an XB1
When I bought the game, the UK Store didn't even have the description (
Cyberpunk 2077: Ultimate Edition (Xbox Series X|S)
It just showed 'Cyberpunk 2077: Ultimate Edition
and didn't have the top line of the description in the store:
Description
Cyberpunk 2077: Ultimate Edition is only playable on Xbox Series X|S as it contains content not available on Xbox One.
This has been recently added after I gifted the game.
The UK Store still shows as 'Playable on: Xbox One, Xbox Series S|X).
Very shoddy practice from Microsoft...
