No notification via Alexa devices

According to the instructions, "when a motion alert is triggered on your Ring device, my Amazon Echo will flash yellow, send an audible chime and announce that someone is at the front door. " This does not happen. I can say, "Alexa show me the front door" and she does (so we're fully connected) but I never get notified via my Alexa (Echo Show devices) and I have confirmed that notifications and motion detection are enabled in the Alexa app. I do get all notifications through my phone with no issue.
