Mechanical Chime does not work when WiFi is down

I was without internet (therefore WiFi also) for 4 days due to hurricane Ian. I have a Video Doorbell Pro 2. The doorbell would not activate the mechanical chime while the WiFi was down. This is a major problem since the doorbell will not notify the Ring app or other device without WiFi. Should the doorbell activate the mechanical chime without WiFi? Or is my doorbell malfunctioning?I had no damage because of the hurricane. Compared to the problems other people have this is minor but I would like to know if my doorbell is bad.
