Since launching six months ago, Twitch Extensions have seen more than 1.5 billion interactions on desktop. From today, they're available on mobile, so viewers can enjoy leader boards, polls, match histories and more, wherever you watch your streams. Not every Extension is mobile-ready just yet -- it's up to developers to decide whether to make theirs mobile-compatible, but you can bet most of them will. However, some Extensions that are already good to go include all-in-one Streamlabs Loyalty, Music, Polls and Games, plus Schedule and World of Warcraft Armory. Make sure your Twitch app is at version 6.0 or higher to take advantage of the update.
