You could do either but I would make note of your settings, you could backup your config but sometimes it may not work with the new firmware. I normally reset at the camera, BUT you will have to resetup your camera as if you just installed it. You could try the reset, not factory, in the menu first...
BUT: You mentioned after the firmware upgrade your camera no longer does motion, I would go double check your settings, it could just be a firmware change/addition...
If none of the above works, I would reach out to Andy
