Hi there,
Thank you for your patience!
After carefully reviewing your case and doing a deep inspection of your code, I noticed that Pinterest doesn’t have the correct URL for your site and this is affecting the sharing activity.
With that in mind, can you edit and add the correct URL?
Pinterest current URL: javascript:void((function()%7Bvar%20e=document.createElement('script');e.setAttribute('type','text/javascript');e.setAttribute('charset','UTF-8');e.setAttribute('src','//assets.pinterest.com/js/pinmarklet.js?r='+Math.random()*99999999);document.body.appendChild(e)%7D)());
Hope this helps!
Best,
