The red bar at the bottom of the Live recording -screen saying ‘Background location not permitted’, means that RaceChrono is not permitted to record the GPS location while the app is in the background, or while the phone’s screen is switched off. In other words this will cause your session not fully recorded, if you have some other app on the foreground, or the phone’s screen is switched off.

You can allow the background location access, and get rid of the error message, by going to “(Phone’s) Settings > Applications > RaceChrono (Pro) > Permissions > Location”, and setting it to “Allow all the time”.
