Ring Video Doorbell 2 - In-Home Chime worked for years - now not working and "in-home" chime not showing under settings

I've had a Ring Video Doorbell 2 for a few years now (at least). We just noticed that it is no longer ringing the mechanical chime in the house (it did work before).I've searched and searched - the response is to go to Device Settings, and then In-Home Chime .... but my App does not have an "In-Home Chime" option anymore. There is a Ring Edge Settings, and then General Settings. Nothing about an In-Home Chime.How do I get the in-home chime working when it doesn't show up in the App settings?
