I'm using Shopify CLI 2.5.0, and no matter what I do, I cannot log in to customer accounts on localhost (development side — http://127.0.0.1:9292/account/login ). So I enter the login info, and it refreshes the page. I am using Shopify theme serve to run the development store.
I found no answer for it anywhere. Someone HERE said that Shopify fixed it on Shopify CLI 2.3, but it did not, at least not for me.
