Use this guide when you changed something in SmartSize or Shopify, but the storefront still shows the old version.

This can happen after editing a size chart, changing button placement, updating product display rules, turning on translations, or saving app embed settings in the Shopify theme editor.

You may see one of these symptoms:

Start with these checks before changing advanced settings.

If you edited a size chart, fit quiz, product display rule, or SmartSize setting, click Save before checking the storefront.

SmartSize shows a saved confirmation after changes are saved.

If you leave the editor before saving, the storefront keeps the previous version.

If you changed app embed settings in Shopify, you must also save the Shopify theme editor.

This applies when you turn on an app extension or adjust app embed button settings.

After Shopify shows Changes saved, return to the storefront and refresh the product page.

A change made in a draft theme does not affect the live storefront.

If the storefront still looks unchanged, confirm that you saved the change in the theme shoppers are using.

For SmartSize app extensions, the App extensions card can help you check live theme status.

Open the product page again and refresh it.

If you are testing several changes quickly, try:

This helps rule out browser cache or an old page state.

If you changed product display rules, confirm that the product you are viewing matches the rule.

Open the chart or quiz in SmartSize and check the matching product list.

If the product is not listed, update the product display rules and save again.

If the issue is related to translations, make sure you are viewing the storefront in the translated language.

For size chart content, confirm that size chart translations are active and that the language shows translated content.

For button labels, confirm that the button label was translated in Shopify Translate & Adapt.

What happens: The editor shows your change while you are working, but the storefront keeps the previous version.

Fix: Go back to SmartSize or Shopify, make the change again if needed, and click Save.

What happens: You changed a size chart, fit quiz, or button setting, but Shopify is not loading the SmartSize extension on the storefront.

Fix: Turn on the relevant app extension in your live Shopify theme:

For detailed steps, see SmartSize button is missing from my product page.

What happens: The chart or quiz is working, but not on the product you are checking.

Fix: Open the product display rules for the chart or quiz and confirm that the product is included. For a quick test, select one exact product and save.

For detailed steps, see Set up product display rules.

What happens: The change appears in the theme editor preview, but not on the live storefront.

Fix: Open the live theme in Shopify and apply the same app embed or app block change there.

What happens: The translation exists, but the storefront still shows the original language.

Fix: Check that the storefront language is set correctly in Shopify and that you are viewing the translated version of the storefront.

For size chart content, see Translate size chart content. For button labels, see Translate SmartSize button labels.

What happens: The app extension is active and the chart or quiz matches the product, but the button still does not appear where expected.

Fix: Try another placement method, such as floating button or app block placement.

For detailed steps, see Choose where the SmartSize button appears.
