Pin It Button not showing after update

I had the plugin installed and working great on my site and then around the time that I updated it, I wanted to try changing out my theme (I went from InfoWay to Adelle). The plugin was updated and I’ve since changed my theme and the hover button no longer appears. I’ve tried changing my theme back to the original thinking it was an issue with the theme but even reverting back does not bring the hover button back anymore. Any suggestions for what to look for or try to get this functioning again?

Thanks!
