difference between alpha and alpha skip-ahead?

In the alpha skip ahead, still no update. "Alpha Skip Ahead" clearly means something else... :')

It is only for alpha and alpha skip ahead unfortunately for now.

It was a 50/50 chance between Alpha Skip Ahead and Alpha rings. I don't know how you would know others have not put in the time but if they are in Alpha Skip Ahead or Alpha rings they have been invited in as people whom file the best most accurate reports.
It is inevitable that some aren't as active as others.

Also you should really be posting your concerns here https://www.reddit.com/r/xboxinsiders

Hi, Wuhey

Unfortunately all the Alpha Skip Ahead spots have been filled. I am sure if you carry on reporting, that when they get spaces, you'll get another invite.y
