How to share an instagram post to my story

Tap below the photo or video in Feed. Tap Add post/video to your story. Tap Add to Story. Keep in mind that when you share someone's post to your story, anyone who views it can see who originally posted it and can view the original account.

If the "Add post to the story" button is absent, you won't be able to share a post to your Story. Only public accounts have access to this functionality. The share button will not be present if you are trying to share a post from a private account, and you will be unable to proceed.
