Hi there @5Julie0, welcome to the Community Forums. Thanks for sharing the details about the issue with your Charge 3.

If you haven't done so yet, please follow the troubleshooting steps provided here Why won't my Fitbit device sync?

As our Support Team has told you, please know Fitbit products are compatible with most devices that have the following operating systems: Apple iOS 12.2 or higher, Android OS 7.0 or higher, and Windows 10 version 1607.0 or higher. For the latest list of devices that support the Fitbit app for Android, see Which phones and tablets can I use with my Fitbit watch or tracker?

Please keep in mind that when a device is not supported and does not meet the require OS we cannot guarantee its functionality with the Fitbit app. It might work at a certain time and then it can stop working out of nowhere after an update. This is because the app is not optimized to that device and any change could impact the performance. 

We routinely test new devices to ensure full compatibility with Fitbit devices and the Fitbit app, and are constantly working to confirm compatibility with new phone models. Be sure to verify that your phone or tablet meets the minimum operating system requirements.
