Unable to Use Preview Update Delta

which one , i see upadte preview omega and update preview delta?

"Why no delta updates"

Sounds like your console is enrolled in the Delta Xbox Insiders preview. If so, you should check the Xbox Insider Forum on Reddit.

The reason you may be getting large 2GB updates is you missed a preview update and the console will download the complete updated OS specific to the Delta preview.

If your only internet access is a phone hotspot I suggest you unenroll from all Insider previews and return the console to the General release OS for xbox consoles.

For example, my console is enrolled in the Alpha skip ahead preview and I do 3-4 updates to the OS a week. It doesn't take long to use 2GB a week just in OS updates.

Hey, Delta. The Blu-ray app update is not a preview version. It is an update that was released to the general public. To enable 3D Blu-ray playback, you need this app update combined with the system update that is currently in Preview.

Hi Volcannon,

Yes, you can rejoin after leaving at any point. It's possible that by joining and gaining exp so that you move up the preview rings to Delta at least so that you may get a future preview update where this issue is addressed and you can test it out for yourself
before those in the Omega ring or not in the preview program. Beta ring previews updates before Delta ring and the Alpha ring, where updates are tested first, requires an invitation to join.

Either way a solution to this will more than likely be tested in the preview program first. News regarding what is included in recent preview updates for the different ring levels can be found here:

If you are in the Insider Program it is currently a known bug.
