Ring Doorbell 2 Solar Charging Questions

There seem to be a number of related issues on this forum regarding the solar charger for the Ring Doorbell 2. I installed my solar charging mount on March 31. At that time I had charged the battery to 100%. After installing the solar charging mount, there was no way to tell whether that device was working or not. The device health section of the Ring app indicated that the doorbell was on battery power, but there is no indicator that the solar charger is attached. Now, almost three weeks later, the battery level is down to 46%. I have been checking the battery level every few days and each reading is lower than the previous reading, so there appears to be no charging happening. I have the charger and doorbell mounted on a south facing wall that gets sunlight continuously throughout the day. I have double-checked all connections and everything is installed according to Ring's requirements. My questions are: 1. Other messages on this forum have indicated that the Ring app is supposed to indicate that a solar charging mount is attached. Is this true? 2. I realize that the charger is supposed to provide a trickle charge, but does it wait for the battery level to drop to a certain percentage (such as 20%) before it begins charging? Unfortunately there seem to be numerous complaints about these issues and Ring has seemingly done a poor job of responding to them. Additionally, the instructions for installing and operating the solar charger are pathetically thin.
