After a month as omega user... Not updated to beta yet :(

They rolled out to the Xbox Insiders Alpha users, as for the rest of us that are Beta, Delta, Omega, or General Public, they have not been released yet.

Sure, open the registration app, and opt out of future betas. Unfortunately, you will not be able to remove the current beta, but after all users are updated sometime this month you will no longer receive beta updates.

One thing to be aware of, you must be active in the insider program for a while, and be selected for the alpha ring. You will likely start in the "Omega" ring, and after 1 month you can move up to the "Delta" ring. 3 months will get you
into the "Beta" ring, etc.

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.

My console was on the Beta ring. I moved it to the omega ring, essentially rolling back several updates. After xbox was setup again, the issue still persisted. I log on today after work apx 16 hours later and normal upload speeds were back .
