It does work, but the user experience is inconsistent at best. I have a Cam Pan v3 that still chimes even when it isn’t supposed to, and I documented and demonstrated in a video last month that the app will sometimes report cameras selected for this feature even when none actually are. This feature clearly still has a lot of problems, and I believe that’s why the “Cameras as Chime” Help Center article was recently amended to remove previous references to extending that feature “soon”.
