Unless you literally turn this feature on, then open the Xbox game bar and go to the widget and select to use it - it’s not just some “always on” thing, you have to open it to use it - then it doesn’t do anything.

“You can disable the Gaming Copilot widget from the game bar, however from experimentation so far the network traffic is still running with the user interface not open — I don’t know if this is a feature or a bug.”
