Hello,

I saw the screenshot you attached and visited your website. You attached screenshots by viewing the website on a real mobile device and by inspecting the website and setting the view to responsive.

I have visited your website and the product styles are the same on real mobile devices.

Actually the mobile view of the product styles inherit from the desktop and style and are different as compared to desktop version.

And there is no option in theme settings that you can change the styles for mobile and desktop separately.

Best Regards.
