Insider Alpha Skip-Ahead Mouse Dashboard & Mouse Bug

Only xbox insider alpha skip ahead users are getting the experimental dashboards.

No, it's not a bug, only 50% of the Alpha and skip ahead users got the new experimental dashboard.

Hi! As far as I know, mouse and keyboard support has so far only been released for Alpha insiders and as always, you should expect to run into bugs here and there. That said, I think mouse support is supposed to be included as well (within the dashboard
and apps at least, as for games the developer have to decide individually if they want to implement M&K support).

You must be invited to become an Alpha Insider or Alpha Skip Ahead Insider, to do so You must Very active in Xbox, doing missions and report the bugs You see in the system, as much as You do this, so You Will be Very close to become an Alpha Insider. You
must be at least in Delta preview to become an Alpha Insider, but You Just need to be an Insider to be invited to become an Alpha Skip Ahead, but this one is very rare to be invited and there is a certain number of people to be invited, no more than that,
If You were not invited to be Alpha Skip Ahead certain time, so You must wait a Second chance when they Will invite New members.
