 * Hello there,
 * I have been using your plugin for a long time and I’m not really sure if this
   has been caused by a recent update of Autoptimize.
 * But I must say I have had great performance results recently and always got near
   100% at gtmetrix. Also, Lighthouse was giving me 100% on each test (mobile or
   desktop, excluding progressive web app).
 * On top of that, with my current settings, I was able to get all green in search
   console regarding core web vitals.
 * But since yesterday, I received some warning messages in search console saying
   that my mobile core web vitals need improvement.
 * When I re-did all the tests that I had done before, I noticed render-blocking
   problems. However, I was using your plugin with the same settings for a long 
   time.
 * So since I did not change anything after I reached my goals regarding performance,
   I’m kinda curious what’s happening. Since it says jquery and render-blocking,
   I just thought that I may ask you first.
 * Do you have any suggestions?
 * I should also add that I did not install any plugins that may cause this. Actually,
   the best results that I got from GTmetrix, Lighthouse had the same set of plugins
   and settings.
 * Eliminate render-blocking resources
    Potential savings of 310 ms Resources are
   blocking the first paint of your page. Consider delivering critical JS/CSS inline
   and deferring all non-critical JS/styles.

 * afraid tests change (gtmetrix was very recently updated, pagespeed insights approx.
   half a year ago).
 * on pagespeed insights jquery is not listed as being render-blocking and given
   jquery is deferred (I guess you’re using AsyuncJS for that) that would be correct,
   if gtmetrix is flagging jquery then it is wrong.

 * now on pagespeed insights you do have 2 render-blocking CSS-files; the a3 lazyload
   one and a generatepress one, both in `wp-content/uploads` which is excluded from
   CSS optimization by default, so maybe remove that CSS exclusion to make sure 
   it is in the inlined aggregated CSS instead?

 * Hey man, thanks a million!!! I think I have been able to solve this issue with
   your suggestions!
 * BTW, I wasn’t using Async JS while I was posting my initial question. Now I’m
   gonna stick with it as well.
 * Excellent job!
 * Cheers
