They’re not slow… they’re not going to do it at all. Shopify has figured out a way to charge you, the end user, for their services while also not providing you with a full suite of tools to employ those services. Instead, they intentionally leave out basic functionalities so that they can create a manufactured marketplace for those functionalities called the Shopify App Store. In this store, independent developers create solutions to Shopify platform shortcomings (proving that those problems CAN BE FIXED) and then sell them to you as “apps” with a monthly fee. I 100% guarantee you that Shopify gets a cut of that fee.
Shopify intentionally creates problems with their platform so that they can make money selling you the “fixes”. This is a borderline scam, and they DO NOT CARE.
