Lazy loading doesn't display images

Dear Madam/Sir,

Perhaps it’s just because of my website’s set-up, but I found images not displaying with your internal lazy loading options set on.

That is, sometimes all images would show, sometimes none would show. If none would show, reloading the page would show the images.

For now, I’ve turned off the lazy loading, but if there are more people experiencing this, maybe something to look into.

Best,

Luca
