When I complete an activity running, cardio, etc. I get a lot of data in the summary including heart rate over time. There is also a chart available called "Time in heart rate zone". It shows the zones and the heart rate ranges for each zone, but has 0% for all zones and doesn't populate the data. I would like to see my % time in each zone, the data is just not populating though it is clearly being tracked as I can see HR over time.
