The most broken app from a large company I've ever seen, so congrats! Snapping rooms side by side doesn't work. Saving your work freezes. You can have high traffic zones OR No-Go zones but not both because the app will crash. Can't make small zones without zooming WAY in which makes you accidentally move a room and then freeze and crash. Did I mention it freezes and crashes a lot? Update the app and it deletes all rooms/zones so you suffer through it again and again. Who greenlit this?!
