Fitbit app won't sync on iOS 12 on my iPhone X

[Andrew23566]

Since updating to iOS 12 the app won't sync any data. Any suggestions.

I had to get a new phone and immediately had to upgrade to iOS 12 and my Fitbit isn’t working either. I removed the app and the device and still nothing.

Hello @Andrew23566, thanks for joining the Fitbit Community, it's great to have you on board. It's nice to see you too @kapricorn1, I hope you're doing well. 

I appreciate your participation in the Forums and for having taken the time to report this situation to us. I'd also like to thank you for letting us know the troubleshooting steps you've tried so far. 

Now, if your Fitbit device is not syncing correctly I would like to suggest you the following:

• Make sure the latest version of the Fitbit app is installed on your phone.
• Make sure there are no other Bluetooth devices around as they might interfere with the syncing process
• Check that your Fitbit device's battery isn't critically low.

If your device still won't sync, try these steps:

1. Force quit the Fitbit app. 
2. Go to Settings > Bluetooth and turn Bluetooth off and back on.
3. Open the Fitbit app.
4. If your Fitbit device didn't sync, restart your phone again.
5. Open the Fitbit app.
6. If your Fitbit device didn't sync, restart it.
7. If your Fitbit device won't sync after the restart, log in to your Fitbit account on a different phone, tablet, or computer and try to sync.
8. If your Fitbit device still doesn’t sync, remove all other Fitbit devices from your account and from the list of connected Bluetooth devices on your mobile device and try to sync.

I hope this can be helpful, give it a try and keep me posted in case you need anything else.
