Missing field “shippingDetails” (in “offers”)

hi. about shippingDetails warning your customers can add these properties to the product schema using the rankmath advanced schema editor or for those products that need shippingDetails on US region they can add this custom code on product page using rakmath schema import.

please make a tutorial article on how to add shippingDetails feature.
i provided complete information in this ticket:
https://support.rankmath.com/ticket/shipping-and-returns-information-on-product-schema/

if you decide to add custom schema code, then you should delete any product schema on page because your product have complete schema that you import.

this warning is only for the US region and just merchants (merchant listings ) but it is still better to prepare an article or a feature for it so that your customers can get the right answer. thank you so much
