App must set security headers to protect against clickjacking.
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.

Hey mate, did you manage to resolve this issue? I’m encountering the exact same issue. The app is functioning fine but somehow fails the Shopify automatic test.

Hi i am facing the same issue. Did you manage to resolve it? Thanks.
