I have an app I built and it seamlessly embedded into my dev store.
I decided to copy that app and only alter the html to reuse the code for another app. I set the app up in Shopify as another app and when I click on 'install app to store' the app appears in a full window rather than being embedded within the Shopify environment.
I reviewed the Shopify install/callback code as well as the front end code and everything appears to be the same as it is with my other app.
What additional steps can I take to resolve this issue and get this app to be embedded within the Shopify environment?
Note: I should mention that the first app that is working is installed in my dev store and the second app I am having issues with is not installed in my dev store. Since they are coming from the same address (ngrok) could this be the issue?
I'll have to test this later by uninstalling the first app and then reinstalling the second app.
