That new update in what month will it be available? June 2021?
In my country there is no summer season, can you please confirm the exact or approximate date for this update?

Thanks for your answer, I already saw the links you sent me, but, the site is still slow, the initial load of the site takes 4 seconds each time I open a section for the first time, I have another website with woocommerce that is much faster and it is on the same server.

I like Xstore, but it is very heavy and my clients get bored waiting that every time they click on a new section they have to wait 4 seconds.

Attached image with google page speed rating of 9%, the website is very slow and is not optimized for efficiency.
Please review these images, google pagespeed rates this website with 9%, and makes many recommendations.
