I have two L50 vacuums and can’t get the 2nd vacuum to show in the app. I was able to click the + and add device and got it mapped. But after that it just disappeared. So then I added it back in again and the map showed up and I was able to run it. Am I going to have to re-add it every time? Or am I missing something? The multi floor management seems to be for using the same robot for different floors.
