HomeKit Home Invitation not delivered
When I invite another member of my family to my HomeKit Home, an invitation is issued but never received by the intended recipient. This has worked in the past, but not at present. The invitation remains in "pending" status indefinitely. The recipient's account is active and functional. For instance, it has access to family calendars and family iCloud, but the problem appears to be user (account) specific somehow. This problem was first seen with both iPhones (issuer and invitee) at IOS version 16.2. We have upgraded both iPhones to the latest IOS release (16.3), to no avail. We have called in to Apple Support, and they tried to help us, but they were not able to.
So it appears we have a family member who cannot receive HomeKit invitations even though that family member interacts perfectly normally with IOS messaging, calendars, iCloud, etc.
Any suggestions?
