I'm having a hard time setting up multiple currencies in my store. I've enabled shopify payments and markets, setup the market countries with their currencies. And still, when I try to use a VPN or change the shipping address to a country with a different currency (I read in some article that checkout currency is determined by address) it still shows me euro which is the default currency. There isn't a currency editor like there was in older tutorials, so I assume it was changed to being automatic/tied with markets. Am I missing something?
