PROBLEM SOLVED: I've always been working from the Wyze app point of view on the iPhone. However, the problem was a setting in the Alexa app on the iPhone. At the home screen of the Alexa app on the iPhone, there is a device entry for the "Front Doorbell." If you select that device, a Live View of the Wyze Video Doorbell comes up. In the upper right corner select the "gear icon." This will bring up a display for the device and ... The Notification Settings! The "Doorbell Press Notification" was already set to ON, but the "Person Detection Notifications" was set to OFF! Wow. How simple. Why didn't anyone including the Wyze support bot mention that! So, problem solved. The iPhone and Echo now announce doorbell presses and person motion detection. Close this problem out, please.
