Modifying a published Instagram post does not generate a new publication in the feeds of followers. Instead, the existing post is updated with the alterations made. This includes changes to the caption, tagged users, location, or alt text. The original post’s URL and publish time remain unchanged.
The ability to amend published content allows users to correct errors or add information without losing engagement metrics associated with the original post, such as likes and comments. This functionality is beneficial for maintaining a consistent online presence and ensuring information accuracy. Prior to this feature, users were required to delete and re-upload content to implement modifications, resulting in lost engagement.
