Hi there, @Trina54. Thanks for stopping by in the Fitbit Community Forums. I'm sorry to hear that your Charge 5 is not syncing anymore. I will do my best to help you! 

As a first approach, I suggest following the troubleshooting steps provided in this help article Why won't my Fitbit device sync?

If the issue persists, please try the steps below in the order listed: 

• Unpair your Fitbit device from your phone's Bluetooth and Fitbit app.
• Unpair other Bluetooth devices that you may also have paired to your phone's Bluetooth settings.
• Force quit the Fitbit app.
• Turn off other Bluetooth connections when not in use. This can help to prevent connectivity issues or Bluetooth interference.
• Shut off your phone and turn it on after 1-2 minutes.
• Turn on the Bluetooth on your phone.
• Plug it into the charging cable and open the Fitbit app.
• Set up your Fitbit device.
• If there is no connection, restart your Fitbit device.
• Once your Fitbit device is paired and syncing, please proceed to set up your other Bluetooth devices to your phone again. 

With the steps above, what I want you to do is to pair your Charge 5 first to your phone's Bluetooth settings before any other Bluetooth device is connected to your phone.

Same here Charge 5 is not syncing to the mobile app (iphone) since Friday 12 Apr 2024.
I have tried 

• Removed the app from Bluetooth. Switched off the Bluetooth.
• Deleted the mobile app reinstalled and switched off and on the phone. 
• Turn on Bluetooth connections.
• I restarted the device.  Swipe down from the clock screen to find the Settings  app. Open the settings app, scroll down and clicked on Restart button. 
• Plug it into the charging cable Press the button located on the flat end of the charger 3 times, pausing for 1 second between presses. Then waited for 10 seconds or until the Fitbit logo appears.  

NONE of the above has worked for me.  

I have noticed many fitbit users are having non-scyning problem. 

Does Fitbit have an answer to this PROBLEM?
My UPDATE as at 16 April 2024
Today-16-Apr 2024.  I tried online chat to ask for a replacement as I am within my warranty. Fitbit assisted with syncing of the C5 giving clear instructions. 
Basically I had to clear the DATA from the Fitbit.   It is now  working.  
With all the reviews I have seen I will not be buying a FITBIT product in the future.

Same for me. With so many reporting similar problems, there is a definite problem with charge 5. Mine is only 16 months old. Very disappointed and next device will be Garmin. I really liked this Charge 5, but the short lifespan and lack of meaningful help from Fitbit is unacceptable.
