There can be many reasons why the device is not syncing. We recommend first checking the source and identifying if the source i.e, Fitbit has the correct data. This can be easily done by closing the Sharecare app and opening the third-party app i.e, Fitbit. First make sure your device is in-sync with this app. Then the next time you open the Sharecare app it should display the same number. In most cases, it may only require you to sync your device to the source app.
