S1: Why did the digital boundary lines shown in my app not synchronized with the mower's actual routes realtime?

Answer:

1. Check the mower’s screen and the Roborock app to confirm that the Wi-Fi, 4G, or Bluetooth signal is connected and stable.
2. Check the GNSS antenna’s indicator light — it should be a solid green color.
3. Check for any available firmware or app updates. If updates are found, install them first.
4. Remove the mower from the Roborock app, then re-bind it by following the setup process again.
5. Restart both the Roborock app and the mower, then try the action again.
6. If the issue still persists, try relocating the GNSS antenna to a spot with a clearer sky view, perform a new map calibration (remapping), and test again.
