My shop https://questfriendz.myshopify.com/ has only GBP and EUR (default) currencies. When a customer adds in either currency a product to the cart, the right currency is shown. However, once reaching the Shopify payment page, it is shown in USD.
See below two screenshots: one from product in cart in EUR and then a second at the Shopify payment page.
Can someone help me and explain to me what I did wrong?
