I contacted customer support and they are replacing my solar panel. They advised anyone having issues with solar charging to contact customer support. Be prepared to have your camera serial number when you contact support.
When I called CS that's the first thing they wanted to do.. replace the solar panel, but I have 2 and they are both slower to charge than they had been. After the agent talked to someone in development they are aware of issues with the iOS app. Also I think that the app only updates the battery level when it performs a "health check" rather than each time the app is opened. I do not know how often the health checks are performed. I've seen times when it's been 2 hours or more. I've not found a way to get it to check it in real time. The CS also couldn't 'see' the solar panel on his end but development said that's an app issue at this time.
With the shorter days coupled with the way the app is updating, I decided to wait and see. Once we got some decent sun yesterday both my spotlight cams charged back up. The one that gets the most sun went to 100%. The other is at 94% this morning but 2 days ago it was at 67%.
