Livestream not compatible with iOS 15?
**Describe The Problem:**
I've recently realized that the livestream, which used to work, doesn't anymore. The screenshots that are taken every 10s still work. The only recent change on my end is that I updated my phone from iOS 14.x to 15.1. Same problem on my spouse's new phone, iOS 15.1 too.

**To Reproduce:**
Click on a specific camera from the Home app. The spinning icon is displayed for a while, then the app says "No response - The camera is not responding".

**Logs:**
Logs aren't showing any error:
