When you tip your favorite creators via chat, they'll receive a notification, which means they'll be more likely to see your message. Plus, you're telling creators that you see them and appreciate their work!
To tip via chat, tap the messaging icon on the bottom of your screen, then tap the compose icon on the top left. Search for your favorite creator, then tap the Sunbeam button on the bottom left (next to the camera icon.) From there, you can select your preferred tip amount, and send a message to the creator you love.
