Adding second resident to Apple Home
I had Apple Home working with various accessories for a year with my iPhone 12 and wife's iPhone 7. I updated to iOS 16.2 to get the new version of Home and Home continued to work for me. Wife got new phone so both of us are on 16.2 BUT she cannot launch the Home app from her phone. I send her AppleID an invitation. Her phone receives and accepts. When she then launches the Home app, she gets the Welcome to Home screen with the Continue button, presses that button, then is brought to an error screen saying "Could not add home 'My Home' A home with a similar name already exists." I've tried changing my Home name, resending the invitation, and logging out of both AppleIDs. My phone shows that she is a resident but she cannot access the app. Trying to remove her as a member from my home using phone or Mac produces "Cannot modify user access."
