My apple watchSE started to malfunction after os 9 update. The activity for exercise calorie burn does not record accurately. Sometimes it showed that i used more than 300 calories but it did not add to the total.
my calorie burn does not record accurately after upgrading to os9. Few times, i burned more than 300 calories and after ending workout, it just not add up to the total, resulting to failure to reach my daily target. Sometimes, my active calorie burn during workout stayed at 0 even if my total calorie recorded was 1000. And i also noticed a lag on the system.
