A. Ensure you are using the latest version of the ECOVACS HOME app. Go to the Google Play Store, search for ECOVACS HOME, and check for updates. If an update is available, install it. This may improve the map editing functionality.

B. Try resetting the map by going to the map settings in the app. Look for an option to delete or reset the current map, then allow the robot to re-map the area. This can sometimes resolve editing issues.
