2023 New Xbox Insider Omega update for new dashboard problem

Through xbox store, just type xbox beta and grab the app and signup then go in and download the new omega dashboard update.

I am enrolled in Xbox update preview Omega. Do I still have the option to get the new dashboard?

will new features be for public of new dashboard for xbox in 2023

Seems a long time to wait. From Beta to Omega, and then GA, just to get a OSU1 file thats older than Beta preview the console is on. A Factory reset is quicker than waiting for a file that may not solve a potential hardware issue.

"on my sons console that is not in the beta but has just updated to the may dashboard,".

As far as I'm aware the new dashboard is only available to Alpha and Alpha Skip Ahead previews.

Edit (22-5-2023) A subset of BETA Insider previews have the new Dashboard

"so just like the previous times, once the osu file is higher than what the console is asking for it will update with no issues."

I would investigate your network access if you need to use a OFFLINE System update file (OSU1) all the time. A stable network is required for all the preview updates that Alpha and Skip Ahead receive each week.

Depending on preview, a Insider console is updated several times over the course of preview.

ASA preview is especially demanding of updates, and if one or two are missed, well, lets just say its not convenient.

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.
