We have our public App, one of Our client reported that the theme app embed is not working on their store.
When we checked in the app admin, the app has both read_themes and write_themes scopes. We also verified that after installation, these scopes are correctly stored in our app database for the client’s store.
However, when we test the same using Postman with the store access token, we receive an “Access denied” error while trying to access theme-related APIs.
Has anyone faced a similar issue, or can suggest what might be missing or misconfigured?
