Since a few days I have noticed that the sleep duration in Garmin Connect is incorrect. For example, I have slept from 23:40 until 6:25, being awake for 7 minutes, but the sleep duration is displayed as 5h28 instead of 6h38. I am using a Vivoactive 3, the incorrect sleep duration is seen both in the Android app and in the web app.
Is this an issue with Garmin Connect? Or might this be linked to my watch?
