Disarmed Mode Detection Disabled - Still Sending Notifications

Hi - I've bought some Ring Stick Up Cameras and added them to my Ring home alarm etc. My wife has the app and I've set up sharing. In DISARMED mode, I've set the cameras to be Live View enabled, but Motion Detection Disabled. When at home, I, therefore, don't get notifications of someone being outside in the garden. My wife cannot change these settings - I assume they are inherited from my app / share - however she gets notified every time the dog pops out the back door! Any ideas? I've searched the forum and I'm maybe not searching the right description of the issue? Thanks.
