My Charge 3 will has not synced with my phone for 3 weeks. Have tried the shut down turn off Bluetooth reset and nothing. The clock is now not accurate as well. Is there a fix?

Hello @CRinard have a warm welcome to the Fitbit Community. 

I appreciate your participation in the Forums and for sharing your experience with us. Note that if your Charge 3 has not synced lately, that's the reason why the time is not showing correctly. Have you restarted your Charge 3 and your phone already? If so, I would like to suggest you to check the following:

• 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.
