Url still not showing preview in LinkedIn or whatsapp

Even after having OG tags put by this plugin, my website links don’t show preview in WhatsApp chat or not allowed in LinkedIn posts.
I don’t know why this is happening, but when I checked my website with LinkedIn post inspector, I found that LinkedIn doesn’t recognize the OG tags of name, title, image and description. When I checked the suggested fix of adding OG tags, I saw that they need a ‘name’ attribute in all the OG meta tags.
Instead of the default tag put by this plugin :
<meta property=”og:title” content=”[Content title here]”>

LinkedIn suggests this :
<meta name=”title” property=”og:title” content=”[Content title here]”>

Adding a name attribute to these meta tags might be the solution to my problem.

Can you help me fix this?

Thank you,
Paul Pavish
