I have some dev stores that have a custom domain on them, for example this one:
Clicking “Log in” next to this sends me to this URL:
https://admin.shopify.com/store/recipekit
when really, the actual .myshopify.com url for that store is something like sweet-store-345.myshopify.com
The real URL I should be sent to should be:
https://admin.shopify.com/store/sweet-store-345
It’s like the custom domain on the dev store is being used as the primary key / identifier for the store. eg. on the above store, I have a custom domain for it that is recipekit.com etc,
