It is an odd sequence, but with my system and the android app, sometimes I will see the graph update but not the total, so if I checked soon after sunrise, I would see "0.1" with the appropriate graph. An hour or two later, when I open the screen again, sometimes I will still see "0.1" but the graph has extended to something clearly above that. Other times, neither the amount nor the graph refreshes. But, for me, navigating to yesterday and back reliably refreshes everything. So it is odd to me that it would go backwards to an old/cached version like that.
