Hi! Thank you for your question.
Please let me inform you that in case you have more than 1 Market, you may use country switcher instead the currency one.
The currencies can be added directly in the Market settings for each Market separately (in case you have Shopify Payments). Once they're added, they'll be available on the storefront end will reflect once the customer changes the country in the switcher.
In case any other question occur, please feel free to contact us via live chat or e-mail: support@langshop.app
Kind regards,
LangShop Team
