Color night video turns black & white and dark a couple of hours after the sun goes down on wired door bell

When I first installed my Ring wired doorbell I got great color videos at night for about a week and now 2 or 3 hours after sunset the picture is black and white, very dark, and has horizontal black lines through it. I have plenty of light on my porch proven by a great video which captured 2 foxes running around on my porch. Tech support has been no help and I haven’t been able to find anything on line. I don’t understand how it looked so good for a week and now it looks great till a few hours after sunset.

Hi @Hobbit. Would you be able to share videos/images of the before and after so we can compare them and possibly identify why this is happening? Thanks, neighbor.
