Small feedback : yesterday I used live tracking « on the fly ». I was pacing a friend on a race, navigating along a route. I activated it while exercice had already started, it worked very smoothly (way more than my initial test when app was released). I have also activated afterwards the gpx display. Almost instantly uploaded and displayed. Well, already said, it would be perfect if fully integrated with SA, but as this point considering you just have to open app live app to make it work, it’s already very convenient and very well executed. Updates since my initial test make it very pleasant and easy to use.
