Video Doorbell 2 infra red/Night Vision

Hi, about a week ago my Video Doorbell 2 stopped switching to infrared when it got dark. There is a light opposite my house that has been there since i got the ring and not been an issue, however if I stand in front of the light over the road, the IR comes on. Has Ring changed the sensitivity or has my VD2 developed a fault? Anyone else noticed or had similar? It seemed to coinside with the enhanced motion zones being activated... Thanks. D
