# Bug Report

### Describe the Bug
<!-- ✍️edit: --> In iOS 15.4.1 (and a couple releases prior) the snapshot views are not updating without forcing a livestream view first. It used to auto pull a snapshot whenever you scrolled to the camera without entering live view.

### To Reproduce
Steps to reproduce the behavior:
 - Open iOS Home app
 - Add a camera as a favorite
 - Force close iOS Home app
 - Open iOS Home app
 - Scroll down to the camera and notice snapshots don't refresh
 - Open live view for your camera and wait for it to load
 - Close live view
 - Notice snapshots for the camera (and sometimes other ring cameras) start to do their snapshot refreshes

### Expected behavior
<!-- ✍️edit: --> Snapshots automatically load and refresh every ~30s without having to enter live view
