Hi - I have two similar websites, both using the Enfold theme (v4.21), and similar in content. My problem is that the thumbnail for the same YouTube link is present on one website, but not the other. As far as I can tell, they were both set up exactly the same. I'm including photos for comparison. The third video on the right is the same for both sites, but you can see the problem. Any advice on how to fix this would be greatly appreciated.
