Apps like AirServer start in small screen and loose connection (Beta 2108.210621-2200)

It's been three days for me also. I try to log into my profile and after maybe 5 seconds a small box pops up at the bottom of the screen saying "Disconnecting from xbox Live." Then the error message comes on that says, "Can't connect to xbox live. Would
you like to check your connection? If you do you will loose progress on your game.... Lower on the screen there's the number 8015190A. Connection works fine. Silver accounts work fine. My gold account on my xbox one works fine.

Yeah, unfortunately the word "beta" has become really diluted when it comes to videogames, people have started to expect a more polished article which really shouldn't be the case. The Xbox (Beta) app is genuinely a beta app, we're testing it, it'll change
and improve. Much like the Xbox Insiders deal with when it comes to Xbox One dashboard and feature updates. We're the guinea pigs and we figure out the small and large issues in an app or a feature. It's part of the process.

Airserver really sucks! Stay away from it and ask Microsoft for a refund!

Sorry to hear it. If you're talking about the Beta app then at the bottom left of the screen you'll see a small arrow. Click on that to pull the left side out. Then click on the 3 dots beside the game to see more information on it

I'm having this problem also. Haven't been able to log in for 3 days. I try to log into my profile and after maybe 5 seconds a small box pops up at the bottom of the screen saying "Disconnecting from xbox Live." Then the error message comes on that says,

fine. Frustrating.
