Hello!
Let us inform you that currencies can be set in our app only if you have set one Shopify Market.
Otherwise, we are blocked by Shopify and can not change the currency.
So, the only way to switch them is within the countly selector.
You may find more information on this matter and about our switchers here.
In case any other question occur please feel free to contact us via live chat or e-mail: support@langshop.app
Best regards,
Langshop Team.
