Important
Although you may be tempted to use the ADD AN APP button to create new apps, you should not use this method. Instead, utilize the Corona build process to automatically generate apps within the Fuse system. This will ensure that the app is properly configured with the Fuse plugin.
I did the registry change and checked the “monetization box” on build but it did not create the app on the dashboard.
