Here a recommendation for a new update, finally remove "cortana settings" it's kind of...

Hi there Trent,

Thanks for reaching out here in Xbox Forums. I understand you have a question on how to connect the Xbox to Cortana. I recommend to check out the following resource article for more information:

• Set up Cortana as a digital assistant for Xbox One

Try this out and let us know the results.

Well, Cortana is no more for Kinect. That feature was removed like around the previous update.

I FIGURED IT OUT! For me at least. Go to settings/System/Cortana Settings/Other Privacy Settings/Speech. Make sure the box is checked that is named "Let xbox and cortana collect my speech info".

The update killed Cortana and this fixed it for me. Best of luck!

Good morning, I had that problem with the Cortana settings locking up, when it locks up press the xbox button on the controller to get back to the home screen and then hit the menu button to go back to the settings, I had to do that a couple of times to
finally get to turn Cortana off.

Seems not all features of Cortana will be available just using a chat mic

Here are a few of the things Cortana can do:

Cortana supports natural language instead of the use of specific phrases or commands. Just say “Hey Cortana” and ask her a question or give her a command!

Use Cortana and voice commands from your headset; no Kinect needed!

Kinect owners can ask Cortana about things like time, weather, and sports scores. For example:

“Hey Cortana, what time is it”?

“Hey Cortana, will I need a jacket today?

“Hey Cortana, did the Golden State Warriors win yesterday?”
