I am looking for some help on this please, as we have finished app development and cannot replicate the error that the Shopify app review team are getting.
We can install the app on 3 different test stores with no error. When Shopify try to install they get a Forbidden error.

Has anyone seen this before? Do you know what might be causing the problem?
