Welcome to the Fitbit Community @Esue! I hope you're doing great!
Let me help you out, try doing the restart again 2 or 3 times in a row then double check that your mobile network is working properly, reboot your tracker and log out and log back in from the app. If the issue persists contact support so they can review your device history and tell you the options.
Let me know how it goes!
