Blood oxygen sensing with Apple Watch Series 10

Mr. Clark, per my last post, did you try again?

Try what? Still no blood ox data since I got the new watch

This is not true. I have an Apple Watch Ultra 2 which was purchased during this ā€œdisputeā€, back in June, and itā€™s had the Blood Oxygen app on it from the beginning. No software updates Iā€™ve done have removed it, either.

Yep, on an Apple Watch Ultra 2, since June.

Was the watch purchased directly from Apple? The Apple support document states that the restriction applies to ā€œunits sold BY Apple on or after January 18, 2024 [emphasis added].ā€

If you bought it through a third-party such as Amazon or Best Buy, it might have escaped the restriction.

ji, do you have sleep set up? For starters, in the phoneā€™s watch app turn on ā€œTrack Sleep with Apple Watchā€. If you get a plot of stages of sleep, then your sensor is working. Sometimes wristband tightness is an issue. If you see the plot and still donā€™t get ox, let us know.

I canā€™t see how it would have escaped restrictions, but it WAS purchased refurbished from a third party. And as I mentioned, doing software updates since purchasing have not removed it.

If it was originally sold before Jan 2024, it would have been before the restriction was imposed.

Apple doesnā€™t remove the functionality after the fact, only at the factory prior to sale.

Presumably Apple could reenable the sensor via a software update if the injunction was canceled, as the hardware still includes the sensor, but the injunction only applies to new devices, not previously sold ones.

Yes, Iā€™ve been tracking sleep for years, and wear the watch all day every day, other than charging for short stints. Still no blood ox measurements.

Ok, step 2. In the phoneā€™s watch app, I have focus set to ā€œMirror my iPhoneā€. In my phone I have Focus>Sleep>Apps>Allow Notifications From>Blood Oxygen.
