@joseph_1979 I gave this a shot and no luck, so I submitted a support ticket. I appreciate the help.

Ever since I updated my Duo with this new firmware update, I no longer get Person Detected notifications on any of my devices for this camera nor do the other occupants in my household. The little WiFi connection indicator has been removed as well. Reboots from the web client, app, and straight up unplugging it has not resolved this issue. Beware of this update if you really need those notifications as I do. Hopefully I can roll it back.
