I would suggest enabling our 'Open Graph - Content' plugin to set this up. You can specify where the description where be pulled from (article text or meta description). Please keep in mind that once Open Graph tags are updated on the page, it may take some time for Facebook to re-scrape your pages. So enable the plugin and manually re-scrape using the
Facebook Open Graph Debugger Tool
or
our debugging tool
to check the new share preview.
Additionally, we have some tips on our
Common Support Questions
for "My Share Preview is incorrect"
If you try these suggestions out and are still having problems, please let us know.
