I have used the live tracking for the 510 and 620 which my wife loves. For the 920 users how would live tracking work for multisport mode? Does it just switch to the different sport in the same live tracking page? Obviously this is more for bike-run since u need the phone.

Goes into live tracking as well as anything else you would want to know about the watch.
