I have an embedded app (URL: embedded-app.com) which contains a URL to a new webapp opened in a new window where merchants will work on (URL: my-domain.com).
Shopify staff has reviewed and required me:
You can only have one consistent UI. Currently, you have an embedded UI that redirects to a non-embedded UI. You can make the non-embedded UI directly accessible for merchants after OAuth and from the app index page.>
How can I change the App URL and Allowed redirection URL in App Setup in Partner Dashboard?
