This morning at 1am I received 2 notifications for motion sensed in 2 adjacent rooms. In the app both rows show in the notifications tab: one for the camera named front hallway and one for the camera named kitchen.
Tapping on both of them show the same front hallway clip.
I have this same thing happen to me, all of the time. The alert is triggered by the light going off in the hallway between the living room and the kitchen. The notifications are titled Living room & Kitchen, however the view is always from the Living room perspective.
