Hi, I’ve been using my Fitbit Sense 2 for less than a month. Recently, I noticed that the device is no longer recording certain metrics such as heart rate variability (HRV), breathing rate, and skin temperature variation — they all show "No data" in the app.
What’s strange is that the sleep score is still showing up normally every day, and I’ve been sleeping for more than 6 hours per night. I’m wearing the device correctly, the sensor is clean and in contact with my skin, and the battery level is fine. I’ve also restarted the device by holding the button until the Fitbit logo appears, but it didn’t help.
I have an active Fitbit Premium subscription, and I’ve already tried syncing manually, uninstalling/reinstalling the app, and checking all settings.
Has anyone else experienced this issue? Could this be a temporary server-side problem, or should I contact Fitbit Support for a replacement?
Any help would be appreciated!
