Hi. My new Fenix 7x is not picking up HRV overnight. Wearing just like my Fenix 6X and since I changed watches have had no HRV or sleep data . Please can anyone advise?
Are you using Battery Saver overnight? If so edit the settings so that WHR is 'Don't Change' (assuming you have it set to On generally) and also change the Phone to 'Don't Change'.
If not using Battery Saver overnight contact Garmin Support.
BTW, whether or not the watch is Primary Wearable is irrelevant. That setting is only in play if you have more than two devices and only means that one is determined to be the 'truth' in situations where data is recorded on more than one device simultaneously. Both devices can collect the same data at the same time.
