There was an error opening your app in the Shopify admin. Your embedded app is redirecting the top frame outside of the Shopify admin URL (https://accounts.shopify.com/lookup?rid=88069f18-cbe2-4995-beaf-47661977398d). Embedded apps are expected to be rendered within the iframe. Learn more about testing your app before submitting.
