Audio-only, video plays
The reason for audio-only is >>> Audio Only <<<<
Your new ads auto-play video in Audio-Only settings.
Many people use audio-only as a way to listen to streams when there isn’t sufficient signal to stream; usually while no Wi-fi is available such as in the car or at work. The pre-roll ads completely freeze the app when there isn’t sufficient signal to play them and there’s nothing for the user to do but refresh the stream and hope the pre-rolls don’t play again, which they usually do. I can’t tell you how many times I have given up on watching a new streamer at work because I can’t get through the pre-roll.
+1 on this, I am using audio only streams extensively in the twitch app and now I'm forced to watch video ads. You can play the ads in audio but I dont want to watch an ad when I'm in audio only mode.
