however when try saving pin, description not show on board add image to. can see on image description present well.

below javascript code using...

 pinutils.pinone({     'url': url,     'media': media,     'description': description   }); 

this html element approach has same result...

<a target="_blank" class="pinit" data-pin-do="buttonpin" data-pin-save="true"' +       ' href="https://www.pinterest.com/pin/create/button/?url=' + protocal + '//' + domain + window.location.pathname +       '&media=' + protocal + '//' + domain + '/' + src.substring(3) + '&description=' + category + ' - ' + subcategory + ' | ' + title + '">' +       '<img width="50px" class="pinitbutton" src="../assets/img/pinit.png"/></a> 

i noticed previous testing had done on same site attaching descriptions no longer is.

has ran issue before? appreciated! thanks!
