“This preview is registered to a different gamertag”

Not everyone who applies to the preview gets in. As far as making a different account, you are certainly entitled to do so however the preview program is limited only to the gamertag that is registered for it.

Access to the preview is by gamertag.

Getting the updates is tied to both the gamertag and the registered console ID. You can have more than one in the preview if you own them

Hey Cleinth!

Sorry to hear about the issue! Since it looks like you have not been invited into the preview program yet, I have bubbled this to the proper teams to have a look.

In the meantime, I would ask a friend to invite you into the preview program if you wish to be able to participate. I will come back to this thread as soon as I get an update!

Hey there i just want to make sure you have the right gamertag since you mentioned it was your son who had the message in their in box on Xbox one giving them access to the program.

If you want to keep the gamertag private you can PM me.

I got a message that group can't be found. I clicked the link given to me by the Microsoft tech during and online chat and ended up here. Can you get me over to the preview forum or get someone to help me out? Thanks.
