Don't have a report issue botton on the alpha skip ahead.

Well if he's in the insider programn then he got a update today had the same issue the alpha & apha skip ahead builds are broken for 50% of the people that are ih that group so don't update your console if you're in alpha or alpha skip ahead

It was a 50/50 chance between Alpha Skip Ahead and Alpha rings. I don't know how you would know others have not put in the time but if they are in Alpha Skip Ahead or Alpha rings they have been invited in as people whom file the best most accurate reports.
It is inevitable that some aren't as active as others.

Also you should really be posting your concerns here https://www.reddit.com/r/xboxinsiders

Fill out a detailed report, giving make and model of headset you use and send it to the development team.

I am in Alpha Skip ahead and sometimes get these issues. You could try backing out of the Insider program, to a public build and seeing if things work.

Remember Alpha and Alpha Skip Ahead are the cutting edge OS builds and can be full of bugs.

as StuartATrueRed states, it is all down to accurate reports. The more you file bug reports, the greater the chance that when they need to top up the Alpha rings, you will get an invite.

if you do get an invite to Alpha or Alpha Skip Ahead, be prepared for lots of bugs and issues.

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