I just installed a Doorbell Pro 2, which worked fine, but now when I click “Devices” in the iPhone app (5.57.0) it only shows that doorbell and the base station, and not the dozen other devices that have always shown. Those devices (contact sensors, etc…) still work: I hear chimes when they are opened, and it shows their name at the top of the app (e.g. “Garage Door Open”). Also the devices appear in the ring.com web-based portal.
The Devices list is also categorized (“Video Doorbells”, “Security”) which isn’t a view I’ve seen on the app before. I updated the Ring app to the latest version as of today.
