Hello! I'm currently setting up my shopify account and noticed my currency is Mongolian Tugrik but I need it to be in US currency. I have tried to change it but it won't allow me to do so because it says, "You've made your first sale, so you need to contact support if you want to change your currency". But I have not had a sale yet. idk how to change it?
Have you tried this method yet? 7 Steps to Convert Currencies in your Store on Shopify
This method uses HTML so you may not encounter that notification.
Hope it helps!
