If your still experiencing issues try turning your Bluetooth off then back on again.
If Restarting and toggling the Bluetooth doesn’t help I would suggest force shut the App and restart. Here’s how:
Turn off your Bluetooth
log out of the Fitbit App
completely shut down your device, wait 1-2 mins then restart your device
once your device fully loads enable your Bluetooth again
now log back into your Fitbit App as you normally would with your email address and password
now sync your device
Lastly please check your iOS settings if this problem persist and try this:
- Open your phone's settings.
- Scroll down, tap Fitbit > Toggle Location to "Always".
- Ensure toggles next to Bluetooth and Background App Refresh are turned ON.
😃Hopefully these suggestions resolve your syncing issue. Please let me know
