Overview
- Users across Reddit and Google/Fitbit forums report that blood‑oxygen and skin temperature metrics vanished or never progress beyond “analyzing” after installing the March update.
- The issue spans multiple Pixel Watch generations, with at least one Pixel Watch 4 owner affected, indicating a broad impact.
- Troubleshooting has produced mixed results, with some success from factory resets or re‑enabling Fitbit permissions and little relief from cache clears or simple reboots.
- 9to5Google notes readings still work on older software builds, suggesting the problem is linked to the latest device update rather than backend services.
- Google has not announced a fix or timeline, and coverage advises waiting for an official patch as some users cite health needs for reliable SpO2 tracking.
