Iframe lazy loading not working

Hello,

I updated the SG optimizer plugin to version 5.7.12 and I am also using Thrive Architect to build my pages. The Thrive Architect plugin is on version 2.6.4.

When I added a video element to the page and add a video URL (Youtube or Vimeo), the preview in the Thrive Architect designer (thumbnail) is shown, but when I publish the page and visit the URL there is no video. It is white space for Youtube and a black box for Vimeo.

Funny thing is that the videos that I added before the update of SG Optimizer and Thrive Architect (I updated both plugins at the same time, so I don’t know which one is causing the issue), are working correctly, only the pages I updated that already have videos are not working anymore and also newly created pages – after the plugins update.

Disabling the option Lazy Load Iframes in SG Optimizer resolved the issue.

Could you please fix the issue in the next releases?

Thank you and best regards,
Rene
