Light not turning on when motion is detected

I have a Spotlight Cam Plus. Previously its light turned on when detecting motion. This has been a great deterrent for crime. However, the light no longer comes on. I can turn the light on remotely, so I know it works, but it only stays on for 30 seconds. I trouble-shot this with Ring support and we went through the whole process of reviewing the setting. When I turn the light setting on, a pop-up appears that says the light will be on for 30 seconds. The setting then turns itself off. Any ideas on how to fix this?
