YOUR CUSTOMERS have been asking for a “default” shipping method for years, so that no matter what, a single shipping method chosen by YOUR CUSTOMER (shopify PAID users) will come up and not change shipping methods to whatever your system deems fit. WE, YOUR CUSTOMERS have been asking for this probably 10 minute coding change on your part for YEARS. We just had to void 100+ shipments because shopify decided USPS standard mail would be best for us, vs. what IS best for us. This is so tiring.
Also, will you stop making unannounced changes, especially without consulting YOUR CUSTOMERS as whether a proposed change is benneficial vs. doing a change anyway which actually makes your platform WORSE!
This is all getting really old, really fast! Its no wonder you stock is in the tank.
