Double Setup

I'm on the map but when I click on the Double icon, I'm unable to connect. What's wrong?

If the Double icon is yellow, the Double app is minimized, the iPad is locked or it's not connected to the wifi. If the Double icon is grey, the Double is in use. Someone else is connected to this device. If the icon is black with a line through it, Double is not connected. This usually indicates that Double is not connected via Bluetooth to the iPad.
