Home kit went blank
I'm not sure if it was after an update but about two weeks ago HomeKit on my wife's iPhone and iPad went blank. This is after it working for years. I tried to invite my wife to our shared home again using my iPad thinking this is the way to resolve this problem. I sent the invitation to two different emails and she never received the invitations on any of her email accounts. I'm not sure what to do to get her HomeKit up and running again. Any ideas on what to try next? Thanks in advance.
iPhone 13, iOS 16
