Issue Identified:
Developers are unable to add checkout extensions to the order status page using the Checkout::Dynamic::Render placement, despite following official Shopify documentation. While extensions appear correctly in the checkout editor for information, shipping, and payment pages, the order status page remains unavailable for drag-and-drop configuration.
Root Cause:
Order status page extensions are in developer preview and only available for local testing on development stores. They cannot be deployed to live stores yet, even with the checkout-extensibility preview enabled.
Workaround:
Developers can test locally by appending a test URL as outlined in the tutorial’s developer preview steps.
Resolution:
As of the most recent update, both the thank you and order status pages have become available for adding checkout extensions. This functionality appears to have been rolled out automatically without requiring manual action, though official documentation hasn’t been updated yet.
Order status page extensions are in developer preview and only available for local testing on developer shops right now. We are actively working on the experience in the checkout editor, stay tuned!
In the meantime, you can locally test extensions by appending the test URL as outlined in this step of the tutorial.
