(Alpha Ring) Newest update has made the MS Rewards app unable to open

Try a power cycle. I am in the Alpha skip ahead ring and can capture Anthem fine. However there is also the possibility that the game itself has an issue. I know there was an update today. You should ensure you are on the newest build of anthem

Seems you have to be invited to join the Alpha ring

The current Xbox One Update Preview rings are:

• Alpha – Open on an “invite only” basis and receives updates at the earliest point in the preview window.
• Beta – Open to Xbox Insiders with a Program tenure of 3 or more months and an Xbox Insider XP Level of 5 or higher. This ring receives updates shortly after Alpha.
• Delta – Open to any Xbox Insider with a tenure of 1 or more months that has reached Xbox Insider Level 2 or higher. Depending on certain edge cases where further attention is required from Alpha or Beta rings, Delta Insiders may receive
  system updates before Beta, though this is not a common scenario. Additionally, while early system updates are not guaranteed across the Delta ring, all Delta Insiders will receive the update prior to GA.
• Omega – Open to anyone and receives system updates shortly before the GA (General Availability) release.

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 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.

You just have to continue to be active in the program, take part in surveys, etc. but Alpha is also by invite only so you would have to wait to be invited into it by Microsoft.

How do the Xbox One Update Preview rings differ and how do I change rings?

There are four Xbox One Update Preview rings, which allow you control when and how often you will get early access to console updates. You’ll gain access to rings based on your activity as an Xbox Insider. If you’ve been invited to more than one ring, you
can switch between them from the Xbox Insider Hub.
