Hey there!
I am having a problem. I have added social metadata in my blog posts but when I share my blog posts on Twitter or Facebook, my site’s favicon is loading instead of featured images.
GP has no control over that.
I can see you’re not using the Featured Image on the single post which is what would generally be shared. But i also see the Open Graph tags for the sharing image.
You will need to check with your SEO or sharing plugin author why it is not working
