Shopify theme app extesion not showing

Topic summary

Main issue: A Theme App Extension works locally but does not appear after deployment to a server. The core app is accessible in the Shopify admin, but the theme extension component is missing in the theme context.

Context and attempts:

  • Ran “npm run shopify app deploy”.
  • Asked how to properly publish a Theme App Extension (i.e., make the theme blocks/sections available post-deploy).
  • A screenshot was shared (no key details captured in text).

Resolution/status:

  • The original poster later provided a link to a solution in another Shopify Community thread (“deploy-converted-theme-app-extension”).
  • No explicit steps or final outcome are documented within this thread; resolution details are external.

Open questions:

  • Exact required steps to publish/activate the extension post-deployment (e.g., versioning, publishing, enabling in a theme) are not recorded here.
