Today I have a large 3 hour gap in the overnight recorded data for; HR, Body Battery, Stress and Respiration. All this data has been successfully recorded on my 955, therefore this is an issue with the Connect app. The app is displaying full overnight HRV data which again confirms that it’s not an issue with overnight sensor recording of HR data.
This issue obviously impacts the accuracy of the cumulative data within the app and needs to be fixed.
