I have a wired spotlight camera that I bought over 2 years ago and Ring told me that only devices purchased after a date in October of this year would work with the new snapshot capture feature which is why I didn’t even have the option in the app. I didn’t believe them so I removed the old camera from my app and re-ran setup and sure enough my old spotlight camera now works with snapshot capture just fine. If this worked on an existing old device ring said it wouldn’t work on surely it should work on officially supported devices with an entirely new setup too.
I get the impression that general Ring support doesn’t really have a grasp on what’s going on here.
