After buying full version, My store became more slower than before and got a Grade F
I contacted the developer and after checking, He told me "our app did its job" at least he didn't check the theme copy before installing that useless thing.
I Don't recommend absolutely.
Return my money back.
Thank you for your review. Our app's main focus is to minify .css, .js, and .js.liquid files for a site, which it was able to accomplish for your store (and removed the warnings that you saw on the web analyzer tools). Unfortunately, minification is only one metric that these analyzer tools measure, so often times it's not enough to change a grade from F to an A. Regardless, I hope that the analysis of your site that I provided during our communications was helpful in determining what you should look at on your site next and I'm sorry for any miscommunication that occurred!
