This is something that I have also noticed and am incredibly frustrated by, why can't I see a breakdown of active/rest/total calories like I could previously? This information is clearly visible on my watch display but if I want to view it in the app (or from previous days) then it's nowhere to be found. Such a stupid change.
Beneath body battery and before the “yesterday” data there should be a blue circle with what you can add back in to what your main page displays like “weight”, “hydration” etc.
