Ring 2 solar charger not charging

I wish I had seen this before I bought the “Solar Charger for Ring Video Doorbell 2” from Amazon. Here on Long Island I have a southwest exposure on my front door and I get consistent sunshine in the early afternoon through dusk. I have had this hooked up for three weeks now and my battery has dropped every day at the same rate as before.

I’m also getting the “Solar Status - Add a Ring solar charger to Extend Battery Life” message in the app (posted in a snip here).

What’s the deal with this? Does it actually work for anyone?
