If I just pause an activity, then resume it without powering off, it resumes counting calories no problem. If I pause the activity and power it off (or the auto power off kicks in), it doesn’t continue to count calories once I turn it back on and resume the activity. It seems like a bug in the firmware as there are no relevant settings I can find. Very frustrating as I makes stops on a lot of my rides and really don’t want to create a separate activity for each segment.
