Cannot Open Certain Apps (Alpha Ring)

Seems you have to be invited to join the Alpha ring

https://support.xbox.com/en-US/xbox-one/console/xbox-insider-program

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.

The new home its for some Alpha skip ahead, but dont worry a certain point the beta ring will have access.

Regards!

Only Xbox Insider Hub members ( Alpha Skip Ahead - Alpha - Beta ) ring, can subscribe to the XGPU. I believe it will be open for everyone to subscribe later this year.

Not just the alpha ring now.

Top 4 rings have the option now or you need the beta app on a windows 10 pc.

Hello,

i am from Germany ....

Now i want to join Alpha Ring, but Microsoft Support tells me, the only way i can join Alpha Ring ist via Invite from another People in the Alpha Ring.

But i dont know anyone in Alpha Ring.

What can i do to join Alpha Ring in XBOX Insider Hub?

Greetings from Germany as well.

Previously, before there were rings, you had to be invited by someone already in the "Xbox Preview Program" as it was called back then.

This was then changed to the Xbox Insider Program, and anyone was able to join by installing the Xbox Insider App, and anyone is allowed to choose a ring up to Beta.

Alpha and Alpha Skip Ahead are only available by invitation from someone at Microsoft, and only if new free slots are available.

You will have to "earn" the privilege to be considered by providing regular and quality feedback, and hope that there are Alpha/Skip Ahead members that provided less feedback, and are removed from the Alpha/Skip Ahead rings.

So the only thing we can suggest is to be patient, and to continue participating in the available activities, and wait for the invitation.
