Describe the bug

App-abreviated namespaces such as $app:my-app work for requesting metafields/metaobjects in the live version of extensions, but not in the editor.

This is the case for both StorefrontApi and Customer Account Api (for customer acc extensions)

Steps to reproduce the behavior:

1. Define a metafield in the Shop resource with an app reserved namespace. eg $app:my-app and whatever key+type+value.
2. In a checkout or customer account extension, request that metafield via the StorefrontApi or the CustomerAccount extensions using the app reserved namespace syntax from before $app:my-app
3. Analyze the payload in the editor and in the Live preview
4. No problems in the live preview, metafield will be found.
5. Problems in the editor, the metafield is not found, is null.

Expected behavior

App reserved namespaces should work both in the editor and in the live preview

I'm experiencing the same issue. This is a critical bug

This is expected. App owned metafields are not yet officially supported and will come later in Q1 per our public roadmap: https://shopify.dev/docs/apps/build/checkout#ui-extensions.

Closing this as we'll post updates to #1138 when official support arrives.

@gil--

This is not an app owned metafield per sé.

As described, this is a Shop owned metafield which is very much supported, as it works 100% in the preview, as stated in the description.

The only problem is in the editor

@muchisx I believe we're talking about the same thing: https://shopify.dev/docs/apps/build/custom-data/ownership#reserved-prefixes. Reserved prefixes (aka $app) are not officially supported in checkout today.
