Camera works but motion isn't detected or recorded. Also fails motion detection test.

[Gerry52]

Up until recently all three cameras detected and recorded when there was motion. Now one, the one I use to recharge batteries when needed, no longer detects motion. It works, as positioning shows me a live picture. But it fails motion detector test. Is it done for and needs to be replaced. Settings across all three are consistent as is the sensitivity

Verify that when Armed, the motion icon is still black...gray means off.

Also make sure the motion setting is from the mode.

if all is ok, you may have to contact Arlo support
