Spotlight light timing

I set my spotlight cam light to stay on for a minute after motion has been detected but it will not save the option in the ring app? I am using batteries for this and it’s on my porch. With it getting it dark sooner I want the light to stay on longer until I get in my house? Or any ideas on how to make the light stay on? image|231x500](upload://xT6xIZcjqgxx16Xp1YxswJYRoRh.jpeg)
