Twitch watch parties. Ok you do have independent control of the two video streams (at least on desktop, I’ve not used it a ton on mobile) but one slider is in the normal twitch position and the other is behind a volume button. Making small tweaks because of the streamer getting loud (I do use ffz’s compressor but it’s not a miracle worker) or cause the audio isn’t of the video is greatly balanced to begin with (looking at you Invincible..) is a pain in the arse… /me tableflip
