Solar panel not registering in app for floodlight

Purchased two solar panels (for two cameras) and a solar panel floodlight. Last night I hooked up one of the solar panels to my Ring spotlight camera and when I open the camera settings, the indicator shows the solar panel is connected and charging. When it comes to my solar flood light, however, the app does not show that the solar panel is connected. Instead, my batter was at 100% and overnight it’s down to 60%. I followed all of the instructions and the solar panel is next to the solar panel I am using for the camera. I removed the floodlight from the app and re-added it. I also uninstalled the Ring app and re-downloaded it. No luck. The second solar panel I purchased for my other camera I haven’t installed yet so I decided to take it out and plug it into my floodlight - even that one is not registering in the app. Wonder what the issue is - is my flood light defective or what other steps can I take?
