The HR widget on the Garmin Connect website now shows readings from the point I wake up till the point I go to sleep. Sleeping readings show up in the timeline and on the mobile app. Why the change? It is annoying when the widgets display different info from other parts of the site or different from the mobile app - consistency would be nice on things like resting HR, too (would be good to have average resting as a reading in the mobile app, not just the widget).
