On the same topic, in mobile the 'hype train' and polls cause the chat to take up half of the screen and can't be disabled in any way. Can you add the option to collapse or exit it?
Someone made a thread about it a month ago and got no response. https://www.reddit.com/r/Twitch/comments/k00zi8/how_to_disable_hype_train_in_the_ios_app/
Sorry, just saw this. I've created a ticket for it, but given this needs Product alignment it might take a few weeks.
