You must begin your troubleshooting by refresh both your smartphone and your watch. A simple reboot often fixes a problem like this. I suggest you reboot your phone first and then turn off your Fenix 5 Plus and turn it back on. Both will reconnect and try to see if the syncing works properly this time.

Another thing you must do is make sure that Bluetooth is working properly on both devices. As you know, it’s the technology that make your watch work with your phone. You may try disabling Bluetooth and then enable it back to refresh the connection.

On your phone, you may also want to remove the Garmin Connect Mobile app and then download and reinstall it. It will make sure that you have the latest version of the app running on your device.

  1. Hold MENU.
  2. Select Settings > System > Reset.
  3. To reset all of the device settings to the factory default values and delete all user-entered information and activity history, select Delete Data and Reset Settings.
  4. If you have set up a Garmin Pay wallet, this option deletes the wallet from your device. If you have music stored on your device, this option deletes your stored music.
