Want a refund

So I’ve tried 3 different plugins with varying results. WP-Rocket has been the ONLY successful one so far in actually improving pagespeed results. Sorely disappointed in this plugin. It straight up DOES NOT WORK. I’ve gone through every single step meticulously and have not been able to see improvement. Listing CSS files to load asynchronously is completely broken, straight up doesn’t work! Switching back to WP-Rocket.
