We are in the review process of our application. Because of the conditions that Shopify is setting our application for the time being will have to be unlisted. To make it eligible for listing in Shopify AppStore we will be integrating the necessary features (airdropping). What is the process than to make an unlisted application listed?
Make sure your app meets all requirements as listed in the documentation.
App review will take some time till all Shopify’s requirements are met. You will have some Shopify app review team members assigned for your app review. You can get help from them if you are having any difficulties or contact the Shopify support team.
