Fix a Fitbit showing a red X with data not cleared sync and try again

Fitbit smartwatch error data not cleared sync and try again

While Fitbits work smoothly most of the time, sometimes things don’t go to plan, and you see a big red X on your Fitbit’s screen with the message that it’s not been able to clear its data. 

Usually, you can get past this screen by syncing to the Fitbit app (or via Fitbit Connect.) 

However, if your Fitbit is stuck on this red X and can’t clear its data or the message keeps reappearing, we detail some troubleshooting steps that fix this error and hopefully get your Fitbit watch working again.

So let’s get to it!

If you connect your Fitbit to more than one mobile device (like an iPhone and an iPad) or computer, that might be the problem. 

It seems that Fitbits work best when they only connect to a single computer, phone, or tablet.

Decide which mobile device (or computer) is most important to you to house your Fitbit data and the app. For any other devices, either remove the Fitbit app entirely or remove your Fitbit from the app.

  2. Go to the Today tab and tap on your profile icon or picture at the top. Profile account icon in Fitbit app

After removing the Fitbit from any additional computers, mobile phones, or tablets, try syncing your Fitbit with the single remaining device using the Fitbit app and see if it clears the red X from your Fitbit’s screen.

Change your Fitbit’s clock face.

Temporarily changing your Fitbit’s clockface often helps get your watch and the Fitbit app to refresh their connection.

  8. Wait for the clockface to download to your Fitbit. Once complete, tap your Fitbit’s screen and see if you can now navigate it without the data not cleared error message.

If the new clockface solves the problem, you can repeat these steps and change the clock face back to your previous one, if desired.

Replace your Fitbit in the Fitbit app

We frequently see this data not cleared error when folks recently factory reset their Fitbits (also called clear user data) but forgot to remove it from the Fitbit app first.

If you factory reset your Fitbit without first removing it from your Fitbit account, follow these steps

  1. Open your phone’s Bluetooth settings and remove the Fitbit from the list of devices by tapping it and forgetting it. iPhone forget Fitbit Inspire in Bluetooth settings

Remove your Fitbit from the Fitbit app and add it back

Reset your Fitbit

If your Fitbit is still showing that its data is not cleared, a factory reset is the last step to try. 

When you reset your Fitbit back to factory standards, you lose any data, like step count and other activity/health information, that was not previously synced to your Fitbit account. 

Additionally, any third-party apps, clock faces, and other customizations are also removed from the Fitbit. 

Before you factory reset, remove your Fitbit from the Fitbit app by following the directions above. 

If you can navigate (swipe) to a different screen on your Fitbit, use these steps to factory reset your Fitbit.

  1. Open the Settings app.
  2. Choose About. 
  3. Tap Factory Reset or Clear User Data. reset to factory settings Fitbit Ionic

For the newest Fitbit watches, try this manual reset process only if you cannot access the software method and your Fitbit is still stuck on the red X screen.

  1. Press and hold the side button until the screen turns off, usually 8-10 seconds. Fitbit watch side button for Sense and Versa 3
  2. As the screen turns off and you feel a short vibration, release the side button and immediately press and hold that button again.
  3. Wait for the Fitbit logo to appear. Fitbit logo on-screen of Fitbit smartwatch
  4. Once it disappears, immediately release the side button and press and hold it again until you feel another vibration.
  5. After you feel the vibration, release the button. This second vibration indicates you’ve started the factory reset.

Additionally, I was a writer, content producer, and editor on the popular tech blog AppleToolBox. So I know a thing or two about teaching others and creating how-to guides! After a cancer diagnosis, I turned to mobile technology like my Apple Watch to help me monitor my health throughout my chemotherapy treatment and later, to regain my wellness once in remission. I love sharing how to understand and use mobile tech, like smartwatches and phones, as a tool for empowerment to live our best and healthiest lives! Connect with me on LinkedIn!


  1. Hi,
    After 2 days solid if trying to fix my red X on my Fitbit, your solution worked. I waded through the Fitbit community and nothing worked. I tried the online help but kept getting bumped out whilst following instructions. I thought it was the end of my Fitbit and I would need another. Great, concise, clear instructions. Thank you so very much, very much indeed!
    Kind regards,
