Hi there, @Ohio! Depending on the model of Spotlight Camera, this operation should be automatic. For the Spotlight Camera Battery version, lights turning on with motion does need to be enabled. This can be altered by visiting the Spotlight Camera in the Ring app, select Device Settings, and then selecting Light Settings. For the Spotlight Camera wired versions, lights are controlled in the same place in the Ring app, but by zones.
I recommend double checking the wifi signal strength, and battery percentage (if applicable), then test this functionality at night. As you mentioned the lights come on via the Ring app toggle manually, this is a great sign that your Camera is fully operational. If these lights still do not automatically trigger with motion, please give our support team a call at one of the numbers available here. We’re taking additional steps to protect our team and help reduce the spread of COVID-19, so this has resulted in longer than normal wait times. If you are outside of the US, please read our response to COVID-19 here to see how to contact support.
