“Using unauthorised accessories compromises your gaming experience. For this reason, the unauthorised accessory will be blocked from use on 11/12/2023,” read the pop-up on the console. It then advised the player to return the product to the store or talk to the manufacturer.
It seems the proper wording is displayed along the code, though, just the article elaborates later. If you think the existence of such code itself is the problem, you're just trying to make someone's life needlessly slow and harder.Also even if they have that nailed, it's still no guarantee. I'm not an Xbox owner but presumably you have a profile with a region (for payments/billing, tax etc) and a selected language. I'd be willing to bet a lot of Brits, Canadians or Aussies have selected "English (US)" language without really thinking through.
We'll see, but I think there will be quite a few confused people in a couple of weeks time regardless.
