You can react to your friends’ posts in the Food Feed using any emoji in your phone’s emoji library.
Tap the smiley face icon below any post, to open up your emoji library. Scroll until you find the one you want, then tap it to add your reaction to the post.
If you want to react to a post with the same emoji that someone else has already used, just tap the reaction you agree with.
You can always tell which reaction to a post is yours by looking for the emoji with the light blue background.
Have fun, and feel free to get creative with your reactions!
