Google+ share counts are not showing

Question

I am using Google+ JavaScript API and currently my Google+ share counts are not showing on the website.

Note: I am using Google+ JavaScript API

This is the code I tried

<!-- Place this tag in your head or just before your close body tag. -->
<script src="apis.google.com/js/platform.js" ; async defer></script>
<!-- Place this tag where you want the share button to render. -->
<div class="g-plus" data-action="share" data-annotation="vertical-bubble" data-height="60">
</div>

Answer 1

They have been retired now so the share counts are no longer available.

Answer 2

Google may have done this to speed up the load time of the Google Plus buttons.
