Hello @Ypoppop, have a warm welcome to the Fitbit Community, it's great to have you on board. 

If your tracker is not syncing correctly I would like to suggest you some troubleshooting tips that have been very helpful for users facing the same situation:

• Restart your Charge 2
• Restart your phone.
• Turn off Bluetooth on your phone through your phone settings (not through Control Center) for 15 seconds, then turn it back on. 
• Make sure you have a strong WiFi signal when syncing.
• Make sure there are no other Bluetooth devices around when your tracker starts syncing. 

If your Charge 2 is still having trouble syncing my best recommendation would be setting up your tracker as a new device to reset the connection between your tracker and your phone. Don't worry, none of the information previously stored in your account will be removed. 

To set up your tracker as a new device:

1. Go to the Bluetooth settings on your phone and check if your tracker is on the list of paired devices. If it is, tap on it and select Forget this Device.
2. Open the Fitbit app and tap on the Account symbol at the top right corner of the screen, then tap on "Set up a New Device"
3. Choose your tracker and follow the onscreen instructions to continue
4. When the app asks you to replace your current tracker, please replace it and continue with the process.

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