Does Shipping Rates Calculator+ work on Shopify POS (Point of Sale)?
Our apps are not compatible with the Shopify Point of Sale (POS) system.
The POS platform is very different from the standard Shopify platform, making all code incompatible. Shopify POS apps have to be coded from scratch for that platform.
