Mine is doing the EXACT same thing. I have a service ticket started via e-mail. I can see the camera on MYDlink Lite on my Iphone…but not Smartthings App. My other camera works on both. Hope to hear back soon.
Yes, the key was to remove the cameras from the Iphone App, then add them back in with the camera hooked up to an Ethernet Cord to the network. Once added, I was able to enable the Wifi setting in the cameras and they now work perfectly. The key was to hook up the camera to the ethernet cord. That must refresh everthing.
