See the last question! I cant acess the preview forum, dont know how to get there. I wait eternal?

This happened in September, September you know, some months ago now...

Of course this is causing this as this is an essential part of the preview program. The preview program is a beta testing program where you get the latest updates for testing and bugfixing.

If you do not want to be part of the program any longer please go to the preview dashboard app and have your console unregistered there. You will be released from the program as soon as the September update is public then. Until that you will receive further
updates every few days.

For further questions please visit the Preview registration forums:

Hi,

The Xbox one update preview is basicly beta. A few bugs or issues my appear in the preview update if the headset worked before your boyfriend accepted the invite, you may want to consider to post the bug on the Xbox One preview update forum and too leave
the preview updates as it is un-stable because it's beta.

If you do not want to leave the beta updates please contact me back and I will see what I can do.

Thanks,

Owen

All Microsoft (including Xbox) beta's will be posted on
http://connect.microsoft.com/. You're extremely early for this dashboard update, as the beta is usually announced after the update is announced (around September / October).
