Xbox conpanion app

The party system needs work for sure, if I join a party on the console, it wont show on my android app (on my phone), nor does it recognize I'm even in a party, and vise versa if I join a party via my android app.

Can you join a party via the companion app and see if that does anything?

The console companion app was discontinued in January along with the rest of Windows 8

You've been supposed to use the Xbox app built into Windows 10 since 2015.

audio party it's only in controller.

go to setting and party options change the input and output it does the same to me

I have done the same thing many times and have never found a way to make the party heard
