Lazy Load (Images not Loading on Scrolling)

Hey,

I am using Smush lazy load feature for 6 months on my site. It was working fine a month ago. However, 10 days ago I just noticed that the images don’t show up automatically. I mean I have selected the Spinners Transition from Display & Animation Setting. However, I also had tried the placeholder transition. But the lazy load images don’t show any animation. Just the extra space is available on the place of the image.

Also, On scroll and even staying 10s 20s seconds on the location of the image. Nothing gets load. However, if I hover the mouse cursor on the place of the image, it gets a load immediately.

I mean normally it should show spinners transition since the image get load. But there is some issue.

You can visit any page or post on my site to check the issue.
