I am working with a Checkout UI Extension. On the storefront, the useLocalizationCountry hook works correctly. However, within the Checkout Editor, the ISO code from this hook does not update when the country in the shipping address selector is changed.
My package versions:
“@shopify/ui-extensions”: “2025.4.0”,
“@shopify/ui-extensions-react”: “2025.4.0”,
“@shopify/app”: “3.58.2”,
“@shopify/cli”: “3.67.2”,
