I've developed a skill for a Doorbell with both the Alexa.DoorbellEventSource and the Alexa.RTCSessionController interface.
If I ask my Echo Show to "Alexa some me the Doorbell" I can view the video. When I send a DoorbellPress Event the Echo Show will announce "Someone is at the Doorbell" however I was expecting the Echo Show to automatically display the feed as the DoorbellEventSource document says:
"When a doorbell event occurs, Alexa plays the doorbell announcement on the selected Echo devices. If the customer selected an Echo device without a screen, the Echo device plays the doorbell announcement. If the customer selected an Echo Show device and the doorbell implements the Alexa.RTCSessionController interface, the Echo Show device plays the doorbell announcement and automatically displays a live feed from the doorbell video camera when the doorbell event occurs. "
How can I find out why the video doesn't display?
