Hello,
I was not wearing my Garmin Fenix 7S Pro from 0900 to 1200 but the watch logged 120+ bpm for three hours and recorded steps. This made my activity calorie go from an average of 500 kcal a day to almost 3000 due to this error. I contacted support and they told me that there is no way to edit this or fix so my history will forever have this period where I burnt 5000kcal for going to the office...
