Delta Preview Forced Update Frozen Console Bug

"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.

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

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

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.

As an Insider I've just gone thru 3-4 updates in the last week, 1 30 minutes ago, and the dashboard has had some changes to location of Tabs (twists) for Gamepass, Mixer, Community and Store.

Also a bug was fixed that was quite annoying and it seems a lot more efficient and responsive.

It is being tested by Beta and now Delta rings, next will be Omega and then after that GA (General Availability) will get released I assume sometime in the near future.

So prepare yourselves. News for Beta, Delta Insiders Update provides further details.
