Hi, all. I wondered if anyone's encountered this one yet. I just updated my iPhone 8+ to IOS 11.1.1. After reboot, my camera app disappeared, and I get a black screen if I try to access the camera through 3rd party apps such as snapchat. Snapchat says it doesn't have access to the camera and when I look at the app restrictions, the camera and facetime are grayed out Any ideas on causes and solutions to this? I've tried restoring the phone multiple times, hard resets, everything, nothing works and the camera was fine until the update.
