It took me a couple of tries but I finally found the watch for me. If you look on my calendar for the activity app, you would see that the days logged are pretty sporadic as I went through a trial and error on which watch to buy (SS, Sport, Size, etc etc). Now that I have my permanent watch, how do nuke all my data from before? I want to start anew. I've tried looking for a "reset all activity data" but can't seem to find it. Any advice?
