Does It Work With Newest WordPress Updates?

I love the fact that this plugin exists; as a novice blogger & with code being something of a foreign language to me the fact that this cuts out the hard work is fantastic!

I followed the ‘as Admin’ steps on the installation page & was able to successfully copy & paste the code from the meta tag into the relevant box, but on returning to the Pinterest site to click ‘finish’ it tells me that it’s not gone through yet & that this sometimes takes up to an hour. It’s been about 5 hours now & still no luck so I’m wondering whether the plugin is compatible with the latest version of WordPress; I’m currently running v.4.3.1 – are you able to advise as to whether this is why it won’t work &/or if there is anything else I should do in order to verify successfully? Thanks again for developing the plugin & thanks in advance for any advice you may be able to give!
