This is our client's site https://4u.am/ . Nopcommerce version is 4.2. Open Graph meta tags already added to ProductTemplate.Simple.cshtml. But when I try to debug with facebook microdata debugger, it doesn't detect any opengraph tag and also said id, image_link, title, description etc required field are missing. Here is the result from facebook debugger result
And in my product page these tags are rendered tags
Could anyone tell what is the reason?
