In our first test with my friends: If you stay on the setup screen after the first lap, the arrows remain visible, but if you exit the setup screen to change engine or fuel, or change your active pilot, the arrows disappear and don't reappear, although the blue indicator lines remain visible. We only tested this on Android devices. However, after your response, we haven't tested it yet; we're waiting for our other friend to come online.

Could you try again and let me know if this is resolved for you?
