I've been developing my first Shopify app and learning everything as I go. I'm using Rails with Postgres and up until now have been using ngrok. Now I'm trying to move everything over to Heroku and in the realm of things I don't understand.
I also found this post where it mentions setting config.embedded_app to false. I did this and pushed to Heroku. Once I did this, I was able to go back to my app url, submit my dev store url and see the screen requesting authority to install the app. I did this and got an error, "The page you were looking for doesn't exist". When I loaded up the store the app was listed. However, when clicking into the app I see the same error.
