To experience the latest firmware features, you can upgrade the firmware to the latest version in the CMF Watch app. To do this, open the CMF Watch app, go to the Device page, and click Device Upgrade. 5. Upgrade the CMF Watch app to the latest version in the Google Play store or App Store to check if this resolves the issue. 6. If the above steps do not resolve the issue, press the button on Watch Pro to enter Settings--System Menu. Click Reset. Then, check again to see if the issue is resolved.
