Currently, Nanit only supports home view on two devices at a time. If two devices or more are viewing Nanit on the home network, only the first and second connected devices will see home view.
If less than two devices are viewing Nanit on the home network and you’re experiencing this issue, make sure your phone is connected to the Wi-Fi network your Nanit is paired to. You can find out which Wi-Fi network Nanit is paired to from the Settings tab. Tap the affected camera on the list, then tap ‘Advanced’ and view the Wi-Fi network name near the bottom. If you find that Nanit is connected to a different Wi-Fi network, you can switch networks by tapping ‘(Re)pair your Nanit with your network’.
