I can’t get a Ring Chime to work with a Ring doorbell

I am using a setup consisting of a Battery Video Doorbell Plus (QR code 30719) plus Chime Pro Second Generation (QR code 94810). The Chime is in the hallway, less than 2M from the bell. The Ring app reports a “strong internet connection”. The network signal strength is RSSI-59, and is RSSI-41 at the front door.In the Ring app, when I use “TEST SOUND ON CHIME”, the chime operates correctly but only once for any test. But when I press the doorbell, the chime is silent, However, the chime nightlight does replicate the doorbell signal.I have cancelled and reinstalled the Ring app. I have also I have also cancelled and reinstalled the chime twice. These have had no effect on the problem.I am very deaf and also have an intermittent speech problem due to a stroke, so telephone calls are very difficult for me. I need a written reply or a help desk email.Thanks and regards, Clive Maier
