Keep image card dismissed when editing the post
When user pastes a link to a post, LinkedIn will automatically generate a card with a site preview.
There are indications that these cards are what is lowering the reach of posts (my theory: https://www.linkedin.com/posts/panta82_linkedin-copywriting-socialmedia-activity-6939348835613753344-cb5Z?utm_source=linkedin_share&utm_medium=member_desktop_web))
When user clicks X to dismiss a link card, LinkedIn will bring it right back the moment the user edits their posts again.
AuthoredIn should keep the card dismissed, unless user reverts their decision.
