Instagram rolled out a new feature that is bound to be a favorite. You can now leave comments on Instagram Stories. Of course, they’re temporary just like the post. There are conditions, though… For private accounts, anyone the poster follows back can now leave comments. And for public accounts, anyone the poster follows can comment, whether or not they are followed back. To turn the feature on, go to "how others can interact with you," then click "comments” and set it to on.
