I am using the FPD on a page in WP via the shortcode method (no WooCommerce). When I share the product on Facebook I have created, there is no image shared. It's just blank. Also when I share on all social media platforms and email the unique link given, it takes me to the page where I can create another one rather than just sharing the picture only.
When I tried this previously, I was able to share the picture only.
Possibly an og-tag issue - I'd need to take a look at a page with the issue, please send a link (or open a support ticket if you don't want to share one here on the forum).
