under iOS Software v2.6.1 (released on Oct 23, 2018) this function seems to have been removed. 😞
it is also not available on arlo.netgear.com - which may mean it is not my current firmware (?) FW v188.8.131.52_21226.
I really need to switch the LED off... any ideas?
This setting is still within your Arlo Baby Settings.
Log in to your Arlo account and navigate to Settings > My Devices > select Arlo Baby > Status Light > toggle Status LED
