Solar wall light will not charge via solar

I’m having an issue with my newly installed solar wall light. It charges via the usb cable, but is losing about 1% of the battery charge per day, and it’s exposed to direct sunlight for at least 6 hours per day. The battery icon in the app has never shown the lightning bolt on it, indicating that the batteries are charging, like my battery powered spotlight cams do, when the solar panel on them is charging. The light threshold is set to 2, and the motion sensitivity is set to “low”. According the event history, it has not sensed motion in 10 days, and has not been turned on, but the battery is still depleting. The battery percentage has never gone up, except when I charge it via usb cable. I have reset the device, and reinstalled it, but the issue has not been remedied. It just refuses to charge via the solar panel on it. Hopefully a ring rep can assist me, as this is very disappointing, because the light is great, otherwise.
