Using watchOS 5 beta 1 and activity tracking seems to be very broken. I tried multiple activities that I do every week and the calories calculated, are way off previous levels. For example swimming today recorded 6 mins of activity with 49 calories burned for a 25 metre pool having done 80 lengths 😀 This was for an hour swim of 100 lengths which normally records about 800 - 900 calories. When I checked other activities they all see to be way off normal levels? Anyone else seen anything similar?
