Hi BHord,

Thank you for posting on the Xbox forums. I'd be happy to help troubleshoot the issue.

First, go ahead and do a hard restart and
power cycle. Hold down the power button on the console for about 10 seconds until it shuts down and then remove the power cable from the Xbox and the power outlet for about 5 minutes. Then re-connect and turn on the Xbox.

If that doesn't help then you will need to try out a soft factory reset.

1. Press the Xbox button to open the guide.
2. Select System > Settings > System > Console info.
3. Select Reset console.

Make sure to select "Keep my games & apps" and have the correct account login information plus your Wi-Fi password ready if you connect wireless because you will need to re-add the account's that were on the Xbox and re-connect to your
network during the reset.

Try out those troubleshooting solutions and let us know the results!

Also experiencing this issue when trying to launch the rewards app on xbox this morning. It’s displaying the splash screen for about 60 seconds before closing the app.

. . . same here when the app is launched the screen becomes black and after a view seconds goes back to the xbox one home screen. i tried uninstalling, rebooting console, and reinstalling wireless display (preview) app and that did not resolve the issue.
Really hope someone from product group support takes notice of this issue and resolves it as w/o this you have to go buy hardware to enable miracasting phone and tablet screens onto console connected big screen.
