Error 500404. Failed to load app. Failed to start app. Could not load layout.json

If starting the app fails, and only shows you error messages like this one, or "Failed to start app: loadPluginConfigurations" that means that our server for configuration of the app can't be reached. (Our new app use a remote configuration that lets us do many cool, new things.) 

The most likely cause is that you're using a network security device such as the Pi-Hole.

You can fix this easily by adding our app partner domain applicaster.com to your device's list of trusted domains.
