I am struggling with parties using Gamebar(PC)

use gamebar for party chat instead then you can pop into gamebar setting and set the default mic and output in there better.

Ok thats what I thought but I dont realy understand the decision.

First of all: Wich App should I use now? The Xbox App or the Gamebar? There are two Apps installed on Windows that have the xbox Party Feature and both of them are lacking in different Features. In the beginning I used the Xbox App, but than oneday all Party
and Game Invitations only appeared for the Xbox Game Bar even when it was disabld in Windows-Settings. That made me switch to the Gamebar. In the Gamebar i was missing Features like seeing who is in a friends party and they adde back a private Voice chat like
on Xbox 360 wich made zero sense. on the Xbox App on the other hand I cant see my friends beeing in a party in the friendlist anymore, also it has no voice overlay and as I mentioned before I get all the Invites for the Game bar even if disabled.

Edit: Also I wanted to mention its still possible to start partys with the xbox app on PC, Smartphone and tablet so why removing the feature for PC players from the Gamebar?

use any mic and use gamebar for party chat.

i was having the same issue it all depends on what you are using aswell. sometimes if you are in party chat using gamebar it will glitch out. you could always do a party in console companion. also if you are using gamebar check the settings to see if push
to talk is enabled or not.+

just use gamebar for party chat, i never open the companion app.
