# Bug Report

### Describe the Bug
I see the following homebridge log

`[5/11/2021, 10:26:31 AM] [Ring] Configuring 2 cameras and 17 devices for location "Maison" - locationId: xxx`

but I only see 1 camera feed in the `Home` app.

A few days ago, I could see both cameras though, and I don't know what might have changed since 🧐

### To Reproduce

I don't really know what to do to reproduce this behaviour on another homebridge installation…

### Expected behavior

I should see both camera feeds
