Hello,
I have observed that few of the data are not synced to Apple Health.
Oxygen Saturation
Respiratory Rate
VO2 Max
This can be done via mobile application update. I also found couple of links which might be useful.
UPDATE: Due to community guidelines links are deleted but can be searched easily on internet
This changes will be common for all series. For example Venu, Forerunner, Fenix etc.
I believe that if the watch is able to calculate such value, same can be synced to Apple Health.
Can you please do the needful?
Thanks
