Alpha skip ahead have removed the recent achievements

I have had issues recently with this, as I'm in Alpha Skip-Ahead, so it is a possibility its that.

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

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

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

There is only a limited number of free slots in Alpha/Alpha Skip Ahead.

If someone in Alpha/Alpha Skip Ahead leaves, or is removed due to inactivity, participants in Beta are invited to Alpha. However, Beta participant invitations are sent out to those, that leave valuable feedback, find bugs, and are most active in the beta
group.

So it's not how long you are in the program, but how valuable your input and bug reporting was in the past.

Added to the fact that invitations are only sent out if there is new room in Alpha, you might have to wait a while to get invited. Just provide good feedback and be patient.
