Has anyone noticed since the last update the heart rate monitor reading at a different level? As an example, I have an original Apple Watch and a series 3. I wear both during workouts depending on which one is charged and they were always pretty consistent. After the big update I have noticed that the series 3 reads at a higher heart rate than the original and higher than it would have before for similar workouts prior to the update. Anyone know why this is occurring? Which one should I trust?
