Thanks for the quick reply! I am adding images through an acf custom block on a post. I am using the ‘Images with Class Set Below’ option.
I’m confirming if I’m able to share the URL, as it’s a client project, and will follow up with link if yes.
When I inspect the lightbox, I don’t see an element with the caption text in the markup. Is there a class name or something I could search for? It doesn’t appear that the caption text is even being used.
