Sense won't sync properly anymore

[1matty1]

Fitbit! Get your technology team working on this sync issue. I've had this watch for 2 and 1/2 years and it has become a weekly annoyance to have to resync this device to my pixel phone. It's making it very difficult to justify not switching to Apple devices. Your help menus are useless

Hi @1matty1 - if you switched to the V4 Fitbit App released in September 2023, which was a rewrite, it's true versions can be less robust than the previous release.

Toggling Bluetooth may simply remedy a loss of connection but there's not much you can do to keep it staying connected other than stop updating to a later latest version once you have a version that is working. New versions are often released which can possibly introduce new issues.

Even so you can try removing the watch Bluetooth entries from the phone, logout of the Fitbit App and swipe off the active window and in Android clear the storage cache and force stop it before restarting the phone and watch.

When you login you may have to add more devices, select your watch and replace to get Bluetooth entries remade (and setup calls again).

Using more than one device with the Fitbit App can also cause problems.

Hi there, @1matty1. Welcome to the Fitbit Community Forums. I'm sorry to hear that your Sense is no longer syncing properly with your Fitbit app. I understand your concern. We're here to help you! 

I agree with @Guy_'s tips and recommendations. Nevertheless, as a first approach, I suggest following the troubleshooting steps provided in this help article Why won't my Fitbit device sync?

If the issue persists, please try the steps below in the order listed: 

• Unpair your Fitbit device from your phone's Bluetooth and Fitbit app.
• Unpair other Bluetooth devices that you may also have paired to your phone's Bluetooth settings.
• Force quit the Fitbit app.
• Turn off other Bluetooth connections when not in use. This can help to prevent connectivity issues or Bluetooth interference.
• Shut off your phone and turn it on after 1-2 minutes.
• Turn on the Bluetooth on your phone.
• Plug it into the charging cable and open the Fitbit app.
• Set up your Fitbit device.
• If there is no connection, restart your Fitbit device.
• Once your Fitbit device is paired and syncing, please proceed to set up your other Bluetooth devices to your phone again. 

With the steps above, what I want you to do is to pair your Sense first to your phone's Bluetooth settings before any other Bluetooth device is connected to your phone.

Thanks for getting back to me. Unfortunately, this only works for a short
period of time and then I'm back to square 1. As I said, my wife has ZERO
sync issues with her Apple devices. Google needs to get this ironed out.

Hi. Thanks for this reply.  It's hopeless and once this battery is finished I'm passing on Fitbit for more reliable tech.  I'm at the point now were I have daily sync issues and I no longer have the patience or appetite to bother with this watch.  I'll go back to Garmin or something I know will be reliable.
