No option to select Activity Zone Mode

[Nathanial]

Seems to be no option to select activity zone mode (Android) . I am subscribed to Arlo Smart and the floodlight cameras are listed under active cameras. The latest firmware is installed for both cameras and the latest app is installed from the Google Play store. One camera is on battery the other is plugged into the solar charger.
There used to be an option for activity zone mode that worked fine but it seems to have disappeared.

There should be a section called Activity Zones under Videos Settings. If that's missing, remove and reconnect the camera to see if that helps.
