Xbox update Preview delta new dashboard

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

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.

"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.

In my understanding the Dashboard experiment, A, B, C selection, is totally random.

As "Both consoles say their OS Version is (19h1_release_xbox_dev_1911.191028-1335)" your consoles are either in the Beta or Delta ring.

Both those rings and Omega ring are getting a preview update News release notes Beta Delta Omega
Insiders today, which you can manually start or wait until it becomes mandatory.

After you do the update, if you want to change rings, it will be the perfect time to change as all those rings will be on the same release. Subject to eligibility.

It's still rolling out so at some point you'll get it on your Series S.

Only if you are in a Insider preview ring! ASA, Alpha, Beta, Delta or Omega.

There has been no notification that the new dashboard has been released to GA.
