Thank you for reaching out to the Community! I’d be happy to provide some assistance with this request, to ensure it gets resolved. To gather a bit more information, are you able to share how you added the currency switcher to your shop?
Depending on whether or not you’re using Shopify Payments, customers will be able to view prices in their local currency automatically. To learn more about this, you can check out our Pricing in Local Currencies document as it touches on this further. Alternatively, you check out the Shopify App Store to install a currency conversion app into your shop.
I look forward to hearing from you however, so I can provide further guidance on this!
