Same here.  Just ipgrafed to iPhone X.  I have shut down, deleted the app, reinstalled, shut down blue tooth.  Repeatedly.  Really?   This is the 3rd time going thru this with the charge 3.  This should NOT be this difficult.  Beyond frustrated. I want my Apple watch back.

Hello @Problemsolver2, @duxml11 and @Msmorize, have a warm welcome to the Fitbit Community, it's great to have you on board. 

I appreciate your participation in the forums and for sharing your experience with us. I would also like to thank you for the troubleshooting steps you've tried so far. Please note that your tracker will not sync nor pair through the Bluetooth Settings on your phone but through the Fitbit app. With that said, I would like to suggest you to try the following steps in order:

1. Turn off Bluetooth on your phone; wait 10 seconds, and then turn it back on.
2. Make sure you have a strong WiFi signal and that there are no other Bluetooth devices around that might interfere with the setup process. (turn off any other phones around)
3. Restart your tracker, then leave it plugged in and charging.
4. If you can't set up after a restart, reboot your phone or tablet and try to set up again.
5. If you can't set up after the reboot, remove all other Fitbit devices from your account and from the list of connected Bluetooth devices on your phone or tablet and try to set up the tracker one more time. 

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