Every week I have differences in intensive minutes displayed on the Edge 1040 and in Garmin Connect. Edge always shows higher values. Of course, all activities are synced, the heart rate recorded by the Edge appears on the Garmin Connect Daily Summary screen.
I was looking for an answer on the forum and I know that there used to be a problem with intensive minutes, but they did not synchronize at all and the heart rate was not displayed on the timeline in the Daily Summary (e.g. here). That problem seems to have been resolved.
Why do the Edge 1040 and Garmin Connect count intensive minutes differently despite correct heart rate synchronization?
