Pool Swim activity is troublesome. First it would not collect OHR data. Fixed that by going into OHR widget settings and turning on "collect HR data during swimming". However, today at the end of my swim the Pool Swim activity crashed the entire watch. I hit stop on the activity and before I could "save" it, the watch crashed. I got lucky. However, HR data was collected in the swim activity but not on the watch. My HR has a blank during that time. Also the Pool Swim activity claims I burned 50 calories even though I had an average HR of 119 BPM for and hour and 17 minutes. Not logical. So my pool swim activity did not add to my Intensity Minutes, Heart Rate, nor Calories. How do I fix this so that I get credit for my swim workouts?
