iOS 18.6.1 and WatchOS 11.6.1 on iPhone 15Pro and Series 10: No Blood O2 data since 2024

Went to Health app on phone, then to both Respiratory > Blood O2, and Vitals > Blood O2 - no new data since 2024 ...


Go to Blood O2 app on Watch, and see this - 'round and round we go'...

Original Title: iOS 18.6.1 on iPhone 15Pro, WatchOS 11.6.1 on Series 10 - still no blood O2
