Hi. I have an 8 months old Fitbit inspire 3 which is showing a blue diamond between the date. The screen is locked and cannot be rebooted. Any ideas please ??

Hi there @Wilsie64! A warm welcome to the Fitbit Community! 

Thank you for letting us know about this situation with your Inspire 3 only showing a blue diamond and for your efforts. 

Have you already updated the Fitbit app? There's a new update available in the Apple Store and Google Play Store.

I suggest you try to restart your Inspire 3 again but with the charging cable as your device is locked:

1. Connect your device to the charging cable. 
2. Press and hold the buttons on your tracker for 10 seconds.
3. Release the buttons. The tracker has restarted when it vibrates and the Fitbit logo shows up.

Then I suggest you follow the instructions described in this article: Why can't I update my Fitbit device?

If this doesn't work, let it run out of charge, then charge it back up.
