What’s happening: Starting May 31, 2021, for article type posts the description, title, and thumbnail will be set from LinkedIn’s URL Preview of the URL only if the description, title, and thumbnail are not provided from the API call. Prior to this change, each field was set from LinkedIn’s URL Preview if the specific field was not set. If a specific representation of the post is desired, set the description, title, or thumbnail fields, rather than rely on automatic preview. Use the Post Inspector tool to determine what the LinkedIn URL Preview looks like.

Probably the API has to be adopted. Please provide a solution.

Thank you
