Hello @Lfitb and @FBituser, welcome to the Community, it's a pleasure to me to greet new members! 
Are you trying to set up your new Charge 2 or is it already setup and not syncing. If you're having inconveniences setting it up, I would like to suggest the following:
- Restart your tracker
- Restart your phone
- Turn off the Bluetooth for 15 seconds and then turn it on once again.
- Make sure there are no other Bluetooth devices around and try to set it up as a new device:
- Open the Fitbit app and tap on the Account tab at the bottom of the screen, then tap on "Set up a New Device"
- Choose your tracker and follow the onscreen instructions to continue
If your tracker is already set up on your account and not syncing correctly, my recommendation would be checking our syncing troubleshooting instructions, as they've been proven very helpful for many members that had experienced these issues.
Give it a try and if there's anything else you need, feel free to reply!
