Inspire 2 won't sync anymore

[Sonnenaufgang]

The inspire 2 won’t synchronize to the iOS app. Everything is up to date.

The data upload is weird and partial, no sleep data and records a handful of steps, for example.

Hi there, @Sonnenaufgang. Welcome to the Fitbit Community Forums. I'm sorry to hear that your Inspire 2 is not syncing anymore. 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 Inspire 2 first to your phone's Bluetooth settings before any other Bluetooth device is connected to your phone.

Now my steps data synchs up, but my sleep data is not appearing in the app. Can you assist?
