Homekit settings missing
I have recently purchased some Hue lights and the new Hue 2.0 bridge (HomeKit Compatible)
I'm running iOS 10 on my iPhone 6s, and the latest available version of tvOS (9.3.3) on a new 4th Generation Apple TV.
The new Home application functions correctly, allowing direct control of the lights. The Apple TV is working correctly for automation tasks that have been configured in the Home application.
However, I am not able to connect to my lights when I'm not connected to the local WiFi network.
Reading various forums, there should be a HomeKit item in the main settings app, and an option to reset the HomeKit configuration in the privacy settings.
Both of these items are missing on my phone. I have factory reset my phone and used an alternative iCloud account and the settings appear, only to go again when I reconnect my own iCloud account.
When I'm logged in with another account HomeKit appears in first picture under settings, and the option to reset the HomeKit configuration appears in the second.
The only information I can find suggests turning Keychain on and off, no change. I have also factory reset the AppleTV, the problem persists.
My guess is that my HomeKit data has got corrupted in my iCloud account, without the option to reset I am rather stuck.
Any ideas to resolve this issue would be gratefully received!
