A new hub update is release today for version 4.01r16
From what I hear this update is specific to address the indoor camera connection stability for it’s wireless and Ethernet connection to the Iris Smart Hub.
You will also notice an upgrade available for your indoor camera when you view your devices page.
However there is no upgrade available being shown for the outdoor camera.
For those who don’t have a camera, you will still see the hub update available for you too.
