LiveStream On Xbox app doesn't work (PC)

I had to download the xbox insider app and join the xbox preview update omega, once I did that I opened up twitch, tried livestreaming, and again it said livestreaming isnt available. But all you have to do after that Is in the middle of the livestream, switch games and go back and it should work, this worked for me and a couple of my friends.

You can use your Windows 10 PC Xbox App to livestream Xbox One gameplay on Youtube. You just will need either OBS or Shadowplay to stream it as well

Hello There ! Sorry for the inconvenience this must have caused you.

Is the issue also present when you go to Xbox.com from your PC and click on Sign In?

Have you tried uninstalling and reinstalling the Xbox app?

Wondering if you have made any changes on your device that might be responsible?

It is also possible that there is a network interruption with the Xbox Live server, the app is out-of-date or your app has lots of corrupted data.

You may try resetting the Xbox app:

1. Go to Start
   
2. Click on Settings
   
3. Select System
   
4. Click on Apps & Features
   
5. Locate the Xbox app
   
6. Click on Advanced Options
   
7. Select Reset
   

After resetting, kindly restart the device for changes to take full effect.

Hi, i have talked 3 times with the Xbox support and one times with the windows support. The last one said me to wait 24-48 hours because he had to talk about it with a specialist. After 2 days i got an email with another 7 fix to try ("Fix problems with apps from Microsoft Store" is the name of the guide) but the problem is still here...
I don't know what to do, the app is unusable.

That generic support doesn't really apply here. The problem is with a PC microphone, not an Xbox One microphone. The Xbox App on PC detects the mic and it works if I start a party via the app, but it doesn't work in any capacity on the Xbox One for parties
or game chat.
