Hey, I am working on an overlay extension that uses the twitch overlay extensions functionality.
Unfortunately we get almost daily information from streamers that our alerts are not displayed on mobile or inside consoles. (Which should actually be Obvios, since Twitch does not support it. Unfortunately streamers do not get it.)
My extension for reference: https://dashboard.twitch.tv/extensions/pe7d87qh2fyeyo2ijifdi1zrnk7evv
