FloodlightCam 2 pro only showing downward view

I installed the camera upside down under my eave to monitor my backyard. Initially I could adjust the view to see outward horizontally but now it only shows downward vertically. The motion adjustment tells me that the full extent has been reached when I try to raise the view back to horizontal. I managed to raise it once in the 4 default settings but it still shows only a downward view. Is this a fault or can you suggest a fix
