Video Doorbell: Motion Detection is not sounding on Chime

I have a hardwired video doorbell and a chime in my hallway. When the doorbell detects motion, the chime no longer emits the usual jingle. In the app under Link Chimes to Front Door, Rings shows 1 Chime Linked, and under Motion Detected it shows 0 Chimes Linked. When I touch Motion Detected, the screen changes to "When Front Door detects motion, your chimes will..." Alert you. But the chime is silent when I test-walk the video doorbell. Can anyone suggest a solution? Thanks.
