I have tried setting up several groups with the Wyze cams. I set up a group with V2 and V3 cameras together - when the phone is held in landscape view, the preview screen shows all of the cameras; however, when the phone is held in portrait view, only the V2 cameras show live shots, the V3 cameras show a black screen. Another group with just V2 and Pan cams shows the shots normally whether it be portrait or landscape.
Anyone else have this experience? It is more of an annoyance, but still it is an issue.
