Preview-alpha vs Alpha: What’s the difference?

If you're in preview alpha or alpha skip ahead, search for Xbox Game Pass Ultimate and you should be able to join.

Hello ,

Are you a member of the Preview Program, and/or have you participated in the Game Pass Program Alpha?

Yes I am in the preview program, no i am NOT in the game pass program alpha

If your console is in the Insider Preview (Alpha or Alpha Skip ahead) try to disconnect all controllers and headsets, and only connect one controller and one headset.

Are you on the Xbox Insider previews? If so, they are changing it for something else. Can't recall offhand but it's in the release notes from a couple weeks back.

@Akame

I got my invite and didn't even read it just assumed it was a beta. This is the first Alpha I can think of on a console.

You are correct FAQ says share all you like but the forum post says different unless this is what they are considering an open Alpha and the post was for closed Alpha but normally all Alphas are closed.....Strange.
