Charge 5 won't sync unless I force the manually sync

I have the most update to date iOS Fitbit app version. My watch doesn’t sync unless I open the app and go to Sync Now. What can I do to get it to sync automatically?

Hi there, @lmp725. Welcome to the Fitbit Community Forums. Thanks for bringing this to my attention and for the troubleshooting steps you've tried. I'm sorry to hear that your Charge 5 won't sync properly. I understand where your concern is coming from , I will do my best to help you with this!

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.
