If you find that the Facebook or Twitter(X) shares are not using the latest text of image this is caused by the platforms caching which can occur if you tested with different content.
The best way to flush the Facebook cache is to go here: https://developers.facebook.com/tools/debug/
and then cut and paste the campaign urls in, and hit DEBUG then SCRAPE AGAIN.
You should do both the campaign and any actions for your campaign as per the below:

When sharing on X (formerly Twitter), images are cached by X's system. After updating your settings, you may need to share the link again to refresh the cached image.
Note: X's card validator tool no longer supports manual cache refreshes (the preview feature was removed in 2023), so there's no guaranteed way to force an update. Cache updates may be delayed or may not occur.
