I've noticed a lot of strange behavior on my 6 camera system since the hub was upgraded a few days ago. I am also seeing random occational lack of motion detection triggers. One of my camera's wired power cables all of a sudden started giving a charging error. All after the hub upgrade. One of my camera didn't reconnect. My doorbell didn't reconnect.
Trying reboots occasionally to see if it helps things. I will monitor for lack of motion detection and see if it persists. Not ideal that a system like this is still so flakey after a firmware upgrade.
