Hello guys!  
Does anyone have any tips for reducing and optimizing the javascript excecution time on CMS in order to reduce the main-thread for improving the performance of the website (mobile) following Google Page Speed recomendation?

The HS recommendation says that including the JQuery library through the Webpage Configurations could solve it but, when i did that all when modules broke down.

Hi, @DEsteva 👋 Can you include a link to one of your live pages that’s scoring this way? I think our community members are more likely to respond if they can see the issue in action.

Thanks! — Jaycee
