Facebook & Pinterest Wrong Image

Hello,

Thanks for developing an awesome plugin!

I tired to test facebook and pinterest but for some reason the correct image is not chosen. I tired clearing facebook image cache and tired this code:

<meta property=”og:image” content=”<?php
if ( has_post_thumbnail() ) {
$full_image_url = wp_get_attachment_image_src( get_post_thumbnail_id(), ‘full’ );
echo $full_image_url[0];}
?>
” />

as suggested here: https://ww.wp.xz.cn/support/topic/no-image-thumbnail-on-facebook-google

but no luck.
Can anyone help me figure out how to have Facebook and Pinterest pick the correct image?
