Just upgraded to the alpha update ring, updated the console but my UI is identical?

Not in a true sense, you can simply just not update your console but then you'd loose valuable UI updates and the ability to connect to the online. The only avant-garde way to get around certain updates would be by signing up for experimental updates through
the Xbox Insider hub, I've noticed (and I'm in the Alpha-Skip Ahead ring which is in the highest tier and gets the most frequent updates) that they utilize space a lot more efficiently on updates focused around UI features and less on pushing the storefront.

If that interests you, you should check this out: https://support.xbox.com/help/account-profile/manage-account/xbox-insider-hub

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.

This has supposedly been fixed, along with a bunch of other stuff, in an update that's available for people in the preview program (alpha ring) now.

So, if you're in the alpha ring, check for updates and you should see it there ready to install.

If you're not in the alpha ring, or you're not in the preview program at all, I expect they'll roll out an update with a bunch of fixes in it to the public fairly soon.

Hi! Just install Xbox Insider Hub app and join to the Insider Beta program to get last alpha ring update for console include a new Avatars.

Hi SnoFox,

This has been a known issue for a while now and acknowledged by the Xbox Preview team and were testing a fix for this issue in the Alpha ring back in December. Since then, there has been no updates but based on this

article I'm assuming the issue was resolved in the Alpha ring preview update but doesn't seem to have gone live yet. There could have been some setbacks or the issue re-surfaced.

This was being tested in the Alpha ring, which is the first ring to test preview updates and requires an invitation to join, and has preview updates with the potential to have the most bugs so it's possible it's stalled in the Alpha ring.

My suggestion is to report the issue through the Xbox Insider Hub app, which you can do so by the report a problem option in the power menu after you have the app downloaded.

If you join the Insider program, eventually it should get pushed to the other preview rings and you can get the fix in an upcoming preview update before it would go live.
