Why i cant download the update from the omega ring?

As I mentioned, if it's not among the ones listed, you should use OSU1

Except that the OP is running an Insiders build (the OS build information is the latest Insiders update) so your advice will likely lead to a broken console!

What the OP posted is a match to the lastest Omega ring update (also seems to match all the updates from all the rings) from 4th February, unless I am missing something:

"Xbox Insider Release Notes – Omega (2202.220202-1734)"

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.

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.

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.

The new update is only out for some Alpha & Alpha skip ahead insiders at the moment.

If you're in the Omega ring then you'll probably be the last ring to get the update before it's released to everyone.
