Telegram's latest update brings some new features, but it looks like it also got rid of a feature. The version 8.0 update doesn't include the Wear OS app. 9to5Google noted that the app has vanished from the Play Store on Wear OS. When you search for it, it no longer appears. But if you have the app already, it should stay put.
The update brings features like unlocking the limits on the size of a live stream's audience. You can now hide captions or the sender's name with messaging forwarding. Telegram will also now show trending stickers, and it improved sticker selection on the Android app. If you send emojis as a single message, these will be animated.
