Blood oxygen feature isn’t working even after updating my iPhone and Apple Watch Series 9

Hi,

I updated both my iPhone and my Apple Watch (Series 9) to version 11.6.1, but the blood oxygen feature is still not working, and I keep getting a message that the application is no longer available.

Does someone have any idea how to solve it?

Thanks

Alon

First, make sure that both devices are up-to-date:



Then make sure both devices are in close proximity with the following settings:

  • AirPlane turned off
  • WiFi turned on
  • Bluetooth turned on
