Hello and welcome to the Fitbit Community @MhairiF
I see you have a syncing issue. I did note that you have a new iPhone 11. Did you remove your Charge 3 from the Bluetooth on your old phone? It can cause conflicts. Try removing your Charge 3 from your old phone if that’s the case and see if that resolves the problem. It that is not the issue please try these troubleshooting steps:
Let’s first try restarting your Fitbit Tracker: Heres how:

Still having an issue? Try trying your Bluetooth off then on again
If your still experiencing syncing issues 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
If your still having syncing issues after restarting your Fitbit Tracker and force shutting your app you can try uninstalling and reinstalling the Fitbit App. You will not lose your data doing this.
Here’s how:
1. Log out of the Fitbit app and force shut the app by swiping up
2. uninstall the Fitbit App from your device
3. now completely shut down your device and wait about 1 min then restart your device
4. once your device has reloaded reinstall the Fitbit app by downloading it from the App Store
5. once it’s installed, log into your device as you normally would with username and password
6. don’t touch anything in the app...just wait until you get a prompt from your Bluetooth.
7. When prompted by your Bluetooth tap yes
8. now try to sync
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
