Hey jpress,
I also noticed via GMetrix the loading of the www-embed-player.js, but in my case it seems it’s loading twice, perhaps because I used the plugin in the page content and the sidebar.
It seems that reducing the number of thumbnails makes the performance a little bit better, but very little.
Would also like to hear if this is known issue.
The page which I’m working is https://familiaquadrada.com/
