My question is if Twitch extensions work on mobile views outside of the official Twitch App.
If that functionality is not available, is it included in any future roadmap work for the Extension functionality?
Generally speaking, extensions only work on channels, when on the main Twitch website and inside the App.
They don’t work in embeds/popups etc.
So as far as I know, no plans as they supplement the whole experience as apposed to just watching the stream. but I’m sure it’s something Twitch may consider if there is enough demand.
