Restoring Maps After Reset

My robot just returned from warranty maintenance, where a hard reset was made. As a result, I had to remap and re-customize (no-go zones, thresholds, custom names, etc.) my map.
It would have been very useful if there were a feature allowing the user to restore a map stored externally after a reset.

My Dreame L40AE has an error message side brush won’t vacuum or mop shuts completely down and it’s not that old! How do u fix this problem??? dorisweaver51@gmail.com

Agreed. iRobot does that. It gets saved in the cloud.
