Pin it button not showing on live site, only when checked from dashboard preview

I have installed the free version of the plugin and set it. Ive checked it from my WP Dashboard preview and everything worked fine, the button was showing as it should. However when logged out from WP, and check the site from several browsers (Chrome, Opera, Explorer) the button was completely missing and wont show up (same from mobile device). You can check the attached link for example.

Could you please help what could be the issue?

Thanks in advance
