Hi David,
Thanks for looking into this.
I think the reason the images are displaying now is that the JS is now set to defer in Litespeed (the images didn’t work on iOS when JS was set to Delay in Litespeed) but issue is the site doesn’t pass Core Web Vitals for Mobile any longer.
What the LiteSpeed said was, “I have just checked the debug logs, the image optimization is being bypassed as you might have errors in your HTML code.” And he sent this screenshot:
