Sleep Data Goes Missing on the Pixel Watch, But Not in Fitbit
Many Pixel Watch owners, particularly Pixel Watch 2 users, are waking up to a confusing message on their wrists: “No recent data. Wear your watch to sleep.” Despite wearing the watch overnight, sleep stats appear to have vanished from the watch’s interface. In reality, the Fitbit backend is still tracking sleep as usual. Users typically find complete sleep logs in the Fitbit app on their phones, making this a display and synchronization problem rather than a total data loss. Restarting the watch has not reliably fixed the bug, and some reports say the issue persists for several nights in a row. For now, the only dependable workaround is to ignore the watch’s sleep tile and review sleep stages and duration in the Fitbit mobile app. The incident adds to a growing list of health-related Pixel Watch bugs and raises fresh doubts about the platform’s reliability.
ECG App Not Working: Heart Rhythm Checks Blocked by App Failures
The Google ECG app, formerly known as the Fitbit ECG app, is also failing some Pixel Watch users at a critical moment. When they try to launch the app to check for signs of atrial fibrillation, they are met with a notification telling them to “Reopen the app and try again.” For some users, this error appears every time they attempt to open ECG, effectively disabling the feature. Reports span multiple generations, including Pixel Watch 2, 3, and 4, suggesting a software or service issue rather than a single hardware batch. Without a clear workaround, users can only ensure that both their Pixel Watch and Fitbit app stay fully updated. According to a support response shared by one user, Google is aware of the ECG app not working and is actively developing a fix, though no timeline has been publicly committed yet.
Pixel Watch Workout Tracking Bug Wipes Out Cycling Sessions
Cyclists relying on Pixel Watch workout tracking have discovered another frustrating glitch: finished bike rides sometimes fail to save at all. Users describe ending a ride, seeing their cardio load increase, and even reaching the “Congrats” summary screen, only to find no record of the workout in the Fitbit app or on the watch afterward. In some cases, only part of a multi-stage ride is preserved, with segments involving auto-pause during stop-and-go traffic disappearing. A Google product expert has suggested that the bug stems from a synchronization error between the watch and Fitbit’s cloud servers. Troubleshooting guidance focuses on clearing the Fitbit app cache on the phone, force-stopping and clearing the Fitbit cache on the watch, reinstalling Fitbit on the watch to rebuild the workout database, and confirming that background data permissions for Fitbit are enabled. Even so, users report that the glitch occurs intermittently, which makes it difficult to verify that any single fix fully resolves the problem.
What These Pixel Watch Bugs Reveal About Software Stability
Taken together, these Pixel Watch bugs point to a worrying pattern in Google’s wearable ecosystem. Fitbit sleep data missing from the watch display, an ECG app not working for multiple watch generations, and cycling workouts failing to sync all affect core health and fitness functions users depend on daily. While sleep logs and cardio load still exist in the background in many cases, the inconsistency erodes trust: a wearable that sometimes loses visible data cannot reliably serve as a personal health dashboard. Recent reports of other health-tracking anomalies—like erratic step counts, SpO2 readings, and temperature data—add further context. As Google transitions Fitbit into a broader Google Health platform, frequent software regressions risk overshadowing new features. Until permanent fixes arrive, users should keep devices updated, regularly confirm that key workouts and sleep sessions are logged, and rely on the Fitbit phone app as a verification tool when the watch’s own tiles or apps appear empty or unresponsive.
