Apple Watches (even Series 9) sold by Apple resellers in the US (Amazon etc) still came with blood oxygen detection, even after firmware updates.

  Only those that shipped before this year. They were getting hard to find even last may.

    Oh is that true? I was under the impression that retailers still were selling the series 9 with it enabled to this day

      I presume they can use over-the-air updates to disable the feature when the device is activated? My watch’s logs always have some OTA stuff.
