Does somebody know why there are no different OS Betas in the omega gamma and beta ring?

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.

Are you in a Insider preview ring?

If so, which ring. ASA, Alpha Beta or Omega?

As an Insiders You gotta make a report for all the bugs You see, You must be in Alpha Ring, this ring is the most unstable, but not more than Alpha Skip Ahead, when You decided to join the Insider Program You knew there were a lot of bugs in the preview
OS, You can change another Ring, Beta, Delta or Omega, but the most stable of them is the Omega ring, now it's You who decid which ring You Will choose to recieve updates or If You Will choose to recieve updates like a normal user.

these are all things you know. I posted this here because Microsoft Support told me to. I understand the program, hence why I am in it.

G'day,

These are the latest Xbox OS and also the Beta, Delta and Omega rings of Insider Preview Program are also on the latest release
to General Availability builds.

Hi, it depends what ring you are in. Currently there is no insider build for Beta, Delta and Omega rings, this means you will be on the current public build.
