Google PageSpeed Insights complaints

I have the same issue, Lighthouse (Google PageSpeed Insights) reports no lazy loading but the plugin is working correctly

Can I see the link to the site page?

Like i said, lazy loading is working but not being picked up in Lighthouse testing

Your template already has a lazy loading script.

The same script is used in the plugin. Perhaps this is the problem.
