Arlo Pro 2 cameras stop detecting motion

[Onegr8dane]

I have two cameras that have stopped reporting motion. I have reset by removing the battery and i have tried turning off/on. 

Doing a motion detection test I get the orange light flashing. However once I try moving in fromt of the camera it does not flash orange, blue or anything and no report of motion is sent.

The cameras worked two weeks ago, so what have gone wrong and how do I fix it?

One camera on the same base station works fine and two cameras on another base station works fine.

If you are using activity zones, try deleting them and creating them again.
