Hi again SlangLabs,
The Shopify internal dev teams have investigated this issue and it appears it was related to our i18nFormat plugin for the i18next library. We’ve shipped a fix to the above plugin to resolve this, so to fix this issue developers should update @Shopify_77 /i18next-shopifyto 0.2.9. If anyone is still experiencing this problem after updating please let us know.
Hope this helps!
