@Mention Features

Instagram is rolling out the @mention sticker on iOS, which makes it even easier to connect with friends in your stories.

After you’ve taken a photo or video in your stories camera, open the stickers tray, tap the @mention sticker,
start typing the name of the account you want to mention and select from the options that appear.
You can then rotate, scale and place your sticker wherever you’d like," said Instagram in a blog post about the feature.
