I believe my question is still unanswered by Ring and I’m not convinced that my second Ring Floodlight will update its firmware ever. I believe it’s a brick. What would help me is to get confirmation from Ring, which I now understand from experience will never happen.
Hopefully others will read these threads if they have similar issues as I have had. Perhaps my contributions here will be useful to them.
