In the latest SDK, 7.4.3, in the VSC simulator, elapsedDistance is stuck at 0.0 meters if you hit START then PLAY. Other simulated metrics work as expected.
Strangely, if you hit PLAY, then START, then elapsedDistance increments ONE time, eg: to 3.123 meters, and then is stuck there. Brandon.ConnectIQ
I tested this on the EDGE 1030, but this is likely a general bug.
