Don't use app a few days, map won't load, it loads in top left and you can't move it! I had to clear cache and data, redraw map rooms to fix it. Now I have the notification "!" blinking and it won't go away! 6 days later, still blinking. If robot won't reconnect after not using a few days, add a new robot, name it the same, and it will go thru connect process and use same map. If you can't draw rooms food, draw small squares overlapping in the room, then merge them as 1 room.
