How to download game preview on insider app

You download the Xbox Insider app on your Xbox One then you open the app and look for a enrollment option for The Insider and the Xbox Update Preview.

Hi ClaimingDuke263,

Have you been accepted onto the Xbox Console Streaming (Preview) program? This should be found in the Insider Content section of the Xbox Insider
Hub app. I have quoted the below from the Xbox Console Streaming (Preview) program FAQ found at the bottom of the page.

“To participate in the Console Streaming (Preview), download the “Insider Hub” app to your Xbox One console. Then, download the “Xbox Game Streaming (Preview)” app on your Android device. Follow the steps in the app on your mobile device to pair your
console and phone. Then, start playing the games you already own! Please note, the initial roll out to Insiders will be phased. For the most up to date details on which Insider rings have access to the Preview, please visit insider.xbox.com.”

That's a preview and it's available for insiders, there's a process to register as insider to get access to it

"To get started, download the Xbox Insider app from the Microsoft Store on Windows. After signing into the app with your Microsoft account navigate to the Previews tab and join the PC Game Pass Southeast Asia Market Expansion preview. Wait for the registration to complete and you’re good to go! Now that you’re in the preview launch the Xbox app which can be found in the Microsoft Store on Windows if it’s not already installed. Sign into the Xbox app with the same Microsoft account that you used to join the PC Game Pass Southeast Asia Market Expansion preview and then subscribe to PC Game Pass from within the Xbox app. After signing up for the service you’re ready to start downloading and playing games from the library! As you start to play games and explore the Xbox app, please help us improve the experience by submitting feedback. To submit feedback, click on the user icon in the top right of the Xbox app and select Feedback from the dropdown."

Is your console pre owned? If it is it may well be still enrolled in the insider preview. Try downloading the Xbox Insider app and seeing if you can remove it.
