Floodlight cam lights on/off no longer function with smartthings

I have used a smart switch to control my lights by using smartthings (automation is when switch turns on, action = ring cam lights on; and when switch turns off, action = ring cam lights off). Worked great. The switch no longer controls the lights, and I see the action in smartthings is no longer lights on/off but rather "unknown action" - and the only available action for the cam in smartthings automations is "refresh". Net is I no longer can control my outdoor lighting with the switches in my house. I replaced my existing outdoor floodlights a couple of years ago with Ring spotlight cams ONLY because there was at least one documented way to use a switch to turn on/off the lights (via smartthings, not Alexa as you would have expected) Now suddenly my entire back yard and my driveway are dark and the solution is that only the one person with a phone who can authenticate to my Ring account can dig into the app to turn on/off the lights? This means you can't just hit the switch and walk out the door, the kids can't turn on the lights, guests can't turn on the lights.... you get it. As useful lights, these are now simply no better than bricks and are about to be dumped (a great investment of hundreds of dollars thrown away). Can anybody tell me how I can turn on/off the lights using a switch now that some unknown Ring change has been made?
