So unless i'm doing something wrong, there does not appear to be an option to restart a workout once it has been canceled.
On this morning's run, I started my scheduled workout, only to realize I wasn't getting some of my external sensors paired so I stopped the activity, made sure to pair the sensors, and when I went to restart, my previous workout was not available to start again. Is there anything I should be doing differently? It seems odd that you only get "one shot" to get a scheduled workout done.
