I debug a shared webpage link in facebook debugger and I get a 200 code as result. The Facebook Debugger can't show the image attached and also it doesen't show while sharing the URL. On Whatsapp and Telegram it works fine. The og:image is present and the image url is working properly. The debugger gives me the warning that I have not a fb:app_id but I don't have a Facebook app, also other links on my site work fine but I could not identify the difference. My website is Wordpress based, I use Yoast SEO for the social tags and use LSCache system. What can I do?
The debugger link is this: https://developers.facebook.com/tools/debug/?q=https%3A%2F%2Fwww.balenaludens.it%2F2024%2Friviste-plato-n-169%2F&locale=it_IT
I always have problem like your situation exactly, but with telegram. In my researches and so many tries in several ways, I found that the problem is your image quality and size.
It should be a small image with a standard quality to show the preview.
If you have all og tags in your head tag, try to set ideal description with a standard medium, acceptable quality with a good size image as your thumbnail.
After updating, make sure that your target platform like Facebook, doesn't cached your url.
