This app works fine until an update, then all the previous detection settings are lost. I was not able to set the Activity Detection Zone. Every time I try to do this, it tells me to log into the camera to live view so that the settings can use the thumbnail. Finally figured it out. You have to remove the pin/passwords and try it a few times before the thumbnail is generated. Once that happens you can enable the pins/passwords. But, really!!! Did no one test this?
