 * Hello, I need support regarding the core web vitals report in Google’s PageSpeed
   insights.
 * When I check a publication of the site (not the main page) – for instance this
   one: [Защо избрах хостинг в Jump?](https://divna.tech/zashto-izbrah-hosting-v-jump/)
   I see that Google recommends to reduce the Java Script and Autoptimize is at 
   the first place.
 * The results for desktop are good but for mobile they are not good. The same is
   with my other site – you may check any publication – for instance this one: [Блефаропластика – оперативна или неоперативна – разлика и ефекти?](https://alena-beauty.com/blefaroplastika-operativna-ili-neoperativna-razlika-i-efekti/)
 * Both the sites use themes made by one author, optimized for Autoptiize – the 
   author recomend using Autoptimze.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcore-web-vitals-reduce-java-script-autoptimize%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * The unused JS is being reported as being Autoptimize’s, but AO merely combines
   all the JS provided by your theme & plugins, so if you (really) want to tackle“
   remove unused JS” then you should look into your theme & plugins (you might be
   able to get some improvement using e.g. “plugin organizer” to only allow plugins
   to work on specific pages).
 * hope this clarifies,

 * I see. I also thought it might be because of the theme, because both the sites
   have this result.
 * Thank you!
