App lost all rooms, history, schedule! Appears to be a complete reset (run time, cleaning runs, and areas all gone) AND my original review is gone! Map has never been very accurate. Doesn't accurately show where robot has vacuumed. Had to recreate all rooms and zones. App is way too slow for the miniscule amount of data being processed. Very disappointed with the interface to the vacuum. Numerous times vacuum ignored return to base while cleaning.
