Spotlight Cam Pro Battery Solar Panel Not Charging Batteries

I have 2 Spotlight Cam Pros. Solar panel did not show connected or charging batteries on either one of them. out of desperation I put 2 batteries in one of them and they came up connected and charging. Which that one is working fine now. (with 2 batteries) Sadly the other one has 2 batteries and the solar panel is not charging the batteries. I have worked with Ring support with no results, and they say the solar panel is defective, but they are out of stock and do not know when they will be back in stock, for about 2 months now. I have read all the articles I can find on this problem and have tried all the fixes that I have seen. But the problem still is there. No charge from solar panel. I have had Ring products for about 3 years now and replaced some of my ring products for the newer version, Big Mistake, I wish I had not done that. Very Disappointed in Ring. Not worth the effort, and headache.
