Overview
- Reports that began with missing SpO2 and skin temperature data after the March 2026 update have expanded to doubled or tripled step counts and extreme calorie totals.
- 9to5Google now observes the same miscounts on devices running older software, indicating the problem likely stems from Fitbit’s servers or app rather than the watch update alone.
- Some users also describe steps disappearing during certain workouts, with elliptical and aerobic sessions cited as especially prone to errors.
- Pixel Watch 2 and Pixel Watch 3 owners who received the March update report widespread issues, while LTE models have not yet been updated, contributing to an uneven rollout picture.
- A Fitbit community moderator suggested resetting the Calorie Target via You → Goals → Nutrition as a temporary workaround, and Google has not announced a fix.
