> What is/was Copilot on mobile and on XBox?

I'd love to explain!

On xbox mobile app you now have a copilot section. It's a chat. If you ask it for current price of something in the store, it will find outdated results from other stores on the internet. That's assuming the "send" button will work, mine often doesn't (it depends on keyboard you use somehow). But app will crash anyway so who cares.

Thank you for your attention.
