My store uses custom liquid code for product filtering. This filtering relies on tags – specifically, each product has a tag in the format plat_X (e.g., plat_NCSoft). When a user clicks on a specific tile on the page, the URL changes to include a filter parameter based on this tag, like so:
This filtering works perfectly fine in the English version of the store. However, as soon as I switch the store to the Polish language (the URL changes to /pl/…), the filtering stops working. To make things more puzzling, even the standard filters from the Shopify Search & Discovery app disappear and become non-functional in the Polish version.
This is very strange to me because the filtering is based on product tags, and the store’s language shouldn’t affect them; tags are language-agnostic.
