In the Barq app when something goes wrong the entire UI language seems to center around "do nothing and tell the user nothing." Example: If content fails to load because the server is busy, the app just doesn't display anything in the selected panel. Another example: If the user provides invalid input or input that is too long, when the user submits the button just turns dark for a few seconds and then pops back. When a user does the wrong behavior or the app has a failure user needs to be informed of what is going on so they don't think they just didn't push the right button or maybe their finger slid off the button.
