Hello,
I see that you added a shortcode to the shop page banner content https://prnt.sc/05YoXoqyNjKy and it displays on the shop page. But I don’t see any product category with the banner in the description, only texts https://prnt.sc/00-UQ61BNwcf
If you want to show a banner on the product category then add the banner shortcode to the product category description.
Regards
