Hello @trixxmanaty
Thank you for your inquiry and I am happy to assist you with this.
As I can see most of the issues that Page speed is reporting are related to CSS. We cannot help you in this case because you are using another plugin for minifying.
But just to give you a heads up, yes, it’s more complex now to increase the mobile score.
The problem is that Page Speed Insights wants you to perform something called ‘Code splitting’. A part of that process means that you figure out what part of the CSS is required to display ‘above the fold’-content — the content you see when you first visit the page without scrolling — and separate that part into a different file. That way, you can load that file the usual way and defer the loading of other stylesheets. You can do the same with scripts by adding async/defer to the script tags. If you’ve done that correctly, the website can show the content a lot faster and loads the content that’s not visible right away afterward. This will improve the “First Meaningful Paint” score to under 1 second.
The problem with the above-the-fold-content is that we cannot figure that out for you. We can only combine and minify the scripts and stylesheets to improve the overall loading time. If you want to apply code splitting, you need to disable JS and CSS minification entirely and ask someone with knowledge about code splitting to help you out. Your theme and possibly some plugins need to be modified to separate the above-the-fold styles into a separate file.
We don’t have such an option in our plugin, as it’s very complicated. Also, no other plugin can do that either.
Using a mobile-friendly theme or AMP plugin may help with this.
