Hello @jane016,
We use get_permalink() function of WordPress for retrieving the permalink of post. I just checked the provided link,the link in post content is different from the preview link that redirect to site,but that’s weird.
The link which is replaced in the {PERMALINK} message format and the link that is submitted to LinkedIn as submitted-url parameter is the same link returned from get_permalink() function.Please check whether your post content or inserted message format for your post contain the link http://scoregolf.com/blog/jason-logan/arccos-caddie-2-0-doubles-down-on-a-i/Five .
If you are using any custom-post type then please check the error log or console for conflicts.
If the issue persist,please let us know .
Thank you.
