Product page refreshing automatically and changing language

[NearlyNormal]

Hello. 

Our language/currency selector does not seem to work. The product pages keep reloading: 

https://shop.bunzaburo.com/en-us/products/スプリングコート-spring-coat?variant=42442481991898

Is this a theme issue? How can we diagnose which JS or thing in the page is triggering the reload? This does not seem to happen with Shopify's stock "free" themes. 

Thanks for any pointers!

Hi @NearlyNormal,

I tested and it works fine. 

When you choose language/currency again, the site will automatically reload to get new options, this is Shopify's default, you can check the paid themes, it all works the same. Refer https://themes.shopify.com/themes?sort_by=most_recent&price%5B%5D=paid&architecture%5B%5D=os2

With not page reload and using ajax, it is supported for old versions of Shopify.

Hope it is clear to you.
