If you have a smartwatch or a Fitbit wristband and it’s not working for you right now with the app, don’t worry about anything: the problem is not with your band, but with the official Fitbit app. Simply put, the data synchronization system is not working properly, as 9to5Google reports and we have been able to verify.
The failure detected is that the application is not able to synchronize with the tracker, that is, everything we are doing with our watch or bracelet does not go to the software (including the Pixel Watch, by the way). Part of the information may appear, but it is just that, “part”: the rest remains lost and is not able to record it accurately.
The error that may appear on the screen is just this, i.e. “Could not sync your device: error”. It does, however, allow you to navigate between the statistics of the previous days, so the information that it is not able to record is the current one, the one that is originating at the moment.
Google, owner of Fitbit after acquiring it in 2021, has commented that it is working hard to solve all the problems. In fact, they indicate that “the interruption of all services” should already be almost completely resolved, although they clarify that in case of continuing to find errors, users should contact through this website.
Our recommendation, and more as owners of one of these bracelets precisely, is the following: restart both the application of your smartphone and the device itself. Leave it off for a few seconds if you can. Once that’s done, restart both the band and open the Fitbit app in question. Try to force sync via the app itself. If the problem persists, wait a while; and if it persists for another day, then go to the portal provided by Google itself for this problem.
