HRV - Heart Rate Variability data not tabulated in my Apple Watch Series 4. How do restart the computation of HRV?
Used new Apple Watch Series 4 since 3 days ago and the device has tabulated HRV daily at various times.
I am not sure what Heart functions/apps measure and tabulate the data but more recent HRV has not posted for almost a day.
Nothing has changed with the device or the point of contact with me, so I am puzzled by the lack of new HRV data.
BPM are being measured and posted on my iPhone X all day.
I have called Apple support twice already and both advisors could not offer any solutions.
