Twitter and Whatsapp sharing not showing image and description

Question

I'm working on twitter and whatsapp share button that actually share the web pages. The Sharing of both working fine but the description and image not showing. I validated my twitter card through twitter card validator it showing perfect but while sharing it doesn't showing description and image and also whatsapp sharing, but facebook sharing that showing description and image. Thanks in advance.

Here is my meta tags:

<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:site" content="@site_username">
<meta name="twitter:title" content="Top 10 Things Ever">
<meta name="twitter:description" content="Up than 200 characters.">
<meta name="twitter:creator" content="@creator_username">
<meta name="twitter:image" content="yourdomain/image">
<meta name="twitter:domain" content="yourdomain">

<meta name="description" content="desc">
<meta property="og:title" content="title" />
<meta property="og:url" content="yourdomain" />
<meta property="og:description" content="description of your website/webpage">
<meta property="og:image" content="yourdomain/image">
<meta property="og:type" content="article" />
