Why isn't my app appearing in the editor for reviewers, even when it works on my dev store?

Extensions

Hi everyone,

I’ve developed a Shopify app that includes a Checkout UI Extension. It functions perfectly and appears as expected in the checkout editor on my development store. However, when I submit it for review to Shopify, the app block isn’t visible in the checkout customization section for the reviewers.

I’ve ensured my instructions are clear and the app is correctly deployed. My test store is a development store, and I’m aware Checkout UI Extensions typically require Shopify Plus.

Has anyone encountered this specific issue during the app review process? Are there common pitfalls or environment differences between a dev store and the review environment that could cause this? Any insights or troubleshooting tips on what to verify or how to communicate this effectively to the review team would be greatly appreciated!

Hi Alija,

If you re-install this on a completely fresh dev store (with the checkout extensibility preview), is the checkout extension appearing as expected?

Hi Liam, it is. I tested it yesterday, created a new dev store with the checkout extensibility preview and it all worked.
