All great suggestions. But Garmin first has to get the Sleep function working reliably before they can implement these types of suggestions. I have had no sleep data for 8 days straight and before that it was sporadic so its just deteriorating. I have also switched from iOS to Android and the problem still persists so its not just an iOS or Android issue. Watch is working in all other features, I am even getting heart rate data during night in the same period where no sleep is detected. I am now wondering if there is something wrong with the movement sensor on my watch.
