After Last BETA UPDATE, I can’t downloading games or buy it!

It's so necessary the last update from windows to download the beta?

The issues with downloading the beta are getting fixed. For more updates please visit Activision Support in twitter if you can. Last update from them:

You only can play Xbox Game Pass PC games with the last build of Windows 10. U want to update to last build, install xbox beta app and after install games.

Thanks ! last question, once I get the beta dashboard update myself will I be able to purchase then and my currency active? IE - if I can never go back to the console that has the beta or don't know who I downloaded my profile to that had it will I never
be able to buy points again on my current console that does not have the beta? hope that question makes sense. So in other words unless I know what console had the beta do I just wait for the update to be able to purchase?
