Php og元标记不适用于whatsapp

我已经在我的网页上添加了元标记，这些标记在一个网页上有效，在另一个网页上无效

当在whatsapp上共享链接url时，元标记可用于此页面

<meta property="og:title" content="Indian Heart Journal now available online: A must read">
<meta property="og:description" content=".. One of the best rated journals for Cardiologists in Asia">
<meta property="og:url" content="https://therightdoctors.com/the-interview/dr-mk-das-consultant-cardiologist-indian-heart-journal-now-available-online-a-must-read">
<meta property="og:site_name" content="@therightdoctors">
<meta property="og:image" content="https://storage.googleapis.com/web-assets/images/IHJ_images/Dr.MKDas2/Dr.MKDas2-large.jpg">
<meta property="og:image:secure_url" content="https://storage.googleapis.com/web-assets/images/IHJ_images/Dr.MKDas2/Dr.MKDas2-large.jpg">
<meta property="og:image:type" content="image/jpeg">
<meta property="og:image:width" content="500">
<meta property="og:image:height" content="400">
<meta property="og:type" content="article">

和上面一样，我为另一个页面添加了元标记，但在whatsapp上共享链接url时，这些标记不起作用

<meta property="og:title" content="Highlights of BIG BP Survey - Hyderabad">
<meta property="og:description" content="BIG BP Survey - Hyderabad.  ">
<meta property="og:url" content="https://therightdoctors.com/highlights/big-bp-survey-hyderabad">
<meta property="og:site_name" content="@therightdoctors">

请帮助我，我哪里做错了。

它们会起作用，只是当你粘贴完整的链接（包括http[s]部分）时，你需要等待几秒钟才能获取描述
