Hello @Henya, thanks for joining the Fitbit Community, it's always a pleasure for me to welcome new members! 

Thanks for sharing your experience with me, I'll do my best to help you with this issue affecting your Charge 2. Tell me, have you restarted your phone and your Charge 2 lately? If so, I would like to suggest you the following steps:

• Make sure the latest version of the Fitbit app is installed on your phone.
• The software on your mobile device is up to date. To check, tap Settings > General > Software Update.
• 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 one more time.
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.
