My Xbox will not update after leaving Omega

Instead of leaving the Xbox Insider program as one Ambassador has suggested you can drop down to a lower ring which receives much fewer updates. For example if you are in Beta ring drop down to Delta or Omega. The Omega ring receives the fewest updates,
usually just before it is released to the general public. This can be managed using the Xbox Insider Hub on your console.

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 .

Would it happen to be Xbox One Update Preview Omega?

And thank you for such a quick reply.

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.

I haven't started my Series X yet to see if there is an update notification. But I checked the Xbox systems update page and there's no mention of a new update. Can you please share the OS version that you're currently on after the new update you just did.

I downloaded the Insider Hub app last night, selected update previews and got into the Omega Ring last night. When I got home from work, turned my Xbox on and went to settings, then console, then updates and there it was.
