Question: Cannot invite family members to HomeKit
Since yesterday I have a problem with our HomeKit system. My wife and son cannot use the HomeKit from the Home app on their iPhones anymore.
We are using my ipad as the HomeKit hub. In their Home app they got a message that they are not connected to the HomeKit system.
I tried everything without success, and therefore finally I removed my house and started from scratch.
Now however a have a new problem. Activation goes OK and I can add all accessories without problems.
When I however try to invite my wife and son in the Home app, I get a message that their AppleID is not registered at iCloud. Very strange because their iPhones are logged to iCloud and work without problems. I tried to login to iCloud using their credentials - also no problem.
Do you maybe have (or had) similar problems and know how to solve it?
Thanks in advance for your help!
iPhone 8, iOS 11.2
