Ring Doorbell (GEN2) with Ring Solar Charger, it never get charged up

I purchased Ring Doorbell (GEN2) and Ring Solar Charger (by Ring). Every day, many hours Sunlight hit Charger Panel, but every day, Ring Doorbell is lossing Power. Even thought no action for all day, just losing Battery Power Every day. Ring Solar Charging Panel seems not charing like Deal Panel. I see Amazon Reviews and so many People are facing similar Issue. Can Ring can fix this issue or improve Solar Charging Panel? Bigger Size Panel is OK. Otherwise, Solar Panel is just Dead Decoration and Value is added...
