Twitch is pushing a notification to users who are subscribed to streamers where free Follower Emotes are available. Normally, you would need to buy them with in-app currency.
This feature is currently in beta and only available if you follow certain streamers.
How to test:
- Open your notifications and check for a marketing push.
- Tap on the notification about free Follower Emotes.
- Tap on the emoji button in the chat and check for free emotes to use.
