Last Upsell - Post-Purchase is loaded via ScriptTag, which means the app will load asynchronously in your store (will load only after the page has fully loaded).

Using ScriptTag, the app will load on all your themes in the Themes Library of your Shopify admin. This will enable you to test the app on any unpublished theme before making it live.

For any questions or clarifications, contact us using the chat icon at the bottom right corner of this page or at support@digismoothie.com.
