What are the steps to enable USB debugging on the Fitbit Versa 4

1. Connect the Versa 4 to a Computer: Plug the charging cable into a USB port on your computer. This is necessary for attempting to establish a connection for USB debugging.

2. Access Watch Settings: On the Versa 4, navigate to the Settings menu. However, reports indicate that the Developer Bridge or USB Debugging option might not be available or functional in the main settings for some firmware versions[7].

3. Enable Developer Bridge/USB Debugging: If the option is available, go to Settings > Developer Bridge and toggle the switch to enable it. You might be prompted to restart the device to activate USB debugging. However, users have reported issues where selecting "Yes" to enable this feature does not work as expected, and the screen may simply turn off without restarting or recognizing the device in Fitbit Studio[1][4][7].

4. Troubleshooting: If you encounter issues, try performing a factory reset. However, this might not resolve the problem, as some users have reported that the settings button becomes greyed out after a reset[4].

5. Fitbit Studio and SDK Limitations: Currently, Fitbit does not support third-party app development for the Versa 4 or Sense 2. The Fitbit Studio, which allowed developers to create watch faces and apps, is being discontinued, and there are no plans to release an SDK for these newer models[1][5][8].

In summary, while the steps to enable USB debugging are outlined, the functionality is not reliably available for the Fitbit Versa 4 due to software limitations and the lack of official support for third-party development.
