Didn't initiate RTH because your RC was probably still powered on and you still had a green LED light. Our devices and the Go app are not really required for flight.

Yes - you are most likely spot on there ... I cannot remember green light on RC - but I wasn't looking at it - I was 'arguing' with my tablet !!
