The "Customize" Button Isn't Showing — Enable the App Embed

The App Embed is what loads Fancy Product Designer on your storefront. If it is not active, the "Customize" button will not appear on your product pages — even if your customizations are set up correctly.

Check Your App Embed Status

Go to the main page of the FPD app and find the App Embed section. It shows the current status for each theme installed in your store.

• Active (green): The embed is enabled. If the button is still not showing, your theme may need additional integration. See: FAQ - Why does the designer not show up on my page.
• Inactive (orange): Click the button in that section. It will take you directly to the App Embeds settings in your Theme Customizer, with the "Fancy Product Designer" toggle already activated. Click "Save" to apply the change.

Enable the App Embed Manually

If you prefer to activate the App Embed yourself, follow these steps:

1. In your Shopify admin, go to "Online Store" > "Themes".
2. Click "Edit" on your active theme.
3. Click the "App Embeds" icon — the third button in the left sidebar.
4. Find "Fancy Product Designer" in the list and toggle it on.
5. Click "Save" in the top right corner.
6. Reload your storefront and check that the "Customize" button now appears.

This is how the active App Embed shows in the App:
