Some of the firmware updates might break your robots. Just in the last month (July 2023), a firmware update caused my robot to drive over the boundary wire, immediately notice it, and shut itself down. And this was happening almost every time the robot approached the wire at a 90° angle. I reported it to Support. And I suppose many others did as well, but they ended up shipping a firmware update a couple of weeks later, largely if not completely fixing the issue.
