Hi there, it's been now more than one year having this issue from time to time (once every 10 activities approx.). After making a nice cycling ride of over 2 or 3 hours, if I have burnt near 1500 kcal, these are displayed on my activity summary in both Edge 1050 device and the activity summary if I look it on Garmin Connect. However, when I go to the calories section on my health Garmin Connect summary, it only appear like if I didn't make the ride, this is 102 active kcal at 13:10 on this sunday. Of course this is not right, as my device is showing over 1500 kcal on that activity.
This happened months ago with my Edge 840, and one of the reasons I upgrade device was to finish with this annoying software issue, but seems it has nothing to do with the device. I did reset and reinstall Garmin Connect on my iphone and the issue keeps occuring from time to time. Of course I contacted the support center but they do not tell me any reason and they say it all looks ok, but of course there is something wrong. Unfortunately I do not find any answer anywhere. Is there someone having the same problem? Of course is not a big deal, the other fitness inputs sync well, like training status, body battery, training readiness, training status, training load... but it really annoys me a lot that the calories for some reason are not syncing well (just sometimes). I hope Garming can give a solution for that
