Optimizing the performance of the main product photo gallery (PageSpeed mobile)
Alex
I noticed that the main product gallery in the theme actually creates problems for LCP on mobile devices according to PageSpeed Insights reports.
Because of this, the yellow zone 50-60 is constantly on mobile.
This is visible even on the demo site.

I’m not sure if the problem is the size of the uploaded image. Because the main LCP delay is due to Element Render Delay. I see a similar situation not only on the demo site, but also on others (there the weight of the images is less than 50 kilobytes).
It seems to me that on the product page there is a mismatch in the priority of script execution, which affects the rendering.
