One issue however is this; I want to screen share with my friends on call so we can all play together and have a good time, however the audio disappears but you are on a phone call. I want this to be fixed. This is because music is one of the most important factors in all of video games and to able to hear these songs I used to love to much with my new friends would literally mean the world to me.
