Geofencing is a fantastic feature that allows the system to arm/disarm when my wife and I are outside/inside a certain proximity of our house. However, it doesn't work consistently on my wifes iphone. Which means we have to manually arm and disarm the cameras. In the Arlo community forums, this is an issue that has been around for over a year. And I'd guess with the new Arlo Ultra having so many issues, the geofencing issue on the Pro2 isn't a priority for the Arlo software team.
