embedded "Pins" not working

A few months ago, I started creating custom Pinterest Pins on Canva and embedding them into my posts using this code before the image: <div style=”display: none;”>
and this code after the image: </div>
It worked great for a while — when I’d click the pin it button, the image would appear and it could be saved to whatever board I liked. Now, the image doesn’t appear when I hit the Pin It button.
What am I doing wrong?

Also, unrelated, I’m using a Featured Image, but oftentimes when I click to save to “Yummly” or other social media – the featured image isn’t picked up and instead, I get random images. Don’t know why.
