Stopped working after upgrading to iOS 17
I have configured a bridge and a single door accessory in home assistant.
They stopped working after updating to iOS 17 my AppleTV & iPhone.

I removed them both from iOS home app and from Home Assistant and tried to reconfigure them as before, but pairing never succeeds. After some minutes, the iPhone shows a message saying that accessory is not reachable and fails.

I am trying to gather the messages from the logs but I recommend avoid upgrading to latest iOS version!
