My active calorie counts have suddenly dropped from their usual range. I haven't put in any extra data or anything, the only thing that's changed is that yesterday I did the time zone update. Since then it doesn't seem to be counting the active calories in the same way.
I do a 4km walk to work every morning. It usually registers about ~120 active calories. Today it's measured 40. It was particularly cold, which perhaps accounts for some of it, but even so...
I've currently done 7,000 steps and have used 85 active calories. I normally hit that by about 2,500 even when it's not as part of one long walk.
My heart rate seems generally low too, even when I'm active in a warm room.
Is this happening to anybody else? Any idea how to fix it?
