All themes have ‘render blocking js and css’ … if you research this further, then you’ll learn it basically means some parts of the page were held up waiting for css and js before showing the top part of the page.
The included booster plugin helps with the theme css/js.
But other plugins, avatars, ads, jetpack, etc. can also impact this.
Trick is to fix everything *except* that as you can get a 90+ score then worry about that last as it’s the least important thing to fix.
*all* themes which include page builders, sliders, mega menus, etc., will have this “issue.”
Again – fix everything ELSE first!
Likely need to see the docs for your CDN.
In our case when we were using Amazon’s CDN in 2014 (not using CDN anymore as it didn’t help us, due to various factors), we had to do the CORS rule in both our site and ALSO on the CDN. I might have posted that in the Newspaper forum 2 years ago (yikes!). In our case with Amazon, we had to edit the ‘bucket’ to do it.
Probably for your CDN there is similar setup where you can enter time to live, expirations, and CORS info. They should have tutorial as CORS is super common problem.

Um… go to your account on themeforest; go to downloads.
List of products you have purchased.
For the Newspaper theme, click the download link, and from the drop down, select “all files.”
This will download to your hard drive.
Open the zip file.
Find the plugins folder.
Open the js_composer zip, upload the folder to your plugins folder.
You can subscribe to update announcements for the theme by checking the box “alert me about updates” or whatever it says on the download page next to each product you bought.

Try clearing your browser cache (seriously).
Fact is, AdSense doesn’t always work, on ANY browser, or in every spot on a page. This is because a certain type of ad may be served, that fails to render.
If you Google this behavior, you will see common complaints going back to 2010 “why don’t my adsense ads load in Chrome,” “why don’t my adsense ads load in Safari” – etc.
The ONLY solution to this we found on some of our news portals (we have been using Adsense since it launched in beta, btw), is to serve up “text only” ads in certain spots.
This is because some advertisers with rich media, whether HTML5 animations, javascript animation, even old Flash ads (which I think are all gone now?), may time out, if loaded from the actual origin server (meaning they are not loading on Google’s cloud, but the actual advertiser content system/CDN). So, when it times out, nothing shows up.
Turning of ‘lazy loading’ completely for the theme, plugins, etc., can help also.
Used to annoy me to see blank ads in places.
Now I will say, I did have a day last week, where going to my own sites on Safari/iOS9/iPad Air, all the ad spots were blank, but they worked in Chrome. So, there be gremlins afoot!
But put another way, it’s NOT theme related — all the ad spots do is inject the code for Google to fetch and render the “spot” — if it times out, nothing fills the spot.
