I’m having the same problem. I’m hardwired, and for months, my ring said it had a solar panel when it did not. It stopped charging, so I removed the device and reconnected. It started working again, but kept the annoying message of having a solar charger. I now notice the latest release, the solar message is gone, but it stopped charging again!!! I removed the device this morning and readded it, so time will tell. The hardwire appears to be working as the hardwire chime still rings when I push the button. I’m guessing it’s another software change that did more harm than good.
