You can add and customize the country and currency selector via the Switcher Customizer on the langify dashboard.

The country switcher will display a range of options based on the countries set up in your Shopify Market settings.

The currency switcher is integrated with the native Shopify currency system. The currency options it displays are based on your setup in the Shopify Payment settings.

Please be aware that langify's currency switcher doesn't have its own mechanism for changing currencies. Similar to a theme's native currency switcher, it is based entirely on your currency setup in the Shopify Payment settings.

Issues related to prices and currency conversion need to be addressed with the Shopify support directly.

If you cannot use Shopify Payment because it is not available for your country, then please have a look at a third-party app for currencies, for example Geolizr. Such currency apps usually have their own currency switchers.

Note that if the currencies are managed via a third-party app, the currency will revert to your shop currency during the checkout process.
