I have tried everything listed with the 16.3 update to invite someone to my home kit and i still cant make it happen . Any advice?

Hello Ocnminded,

Let's perform the steps below which can help resolve issues with invites for HomeKit:

"If you can't share control of a home

• To invite people to control your home while you're away and edit permissions for them, you need to set up a home hub. If you don't have a home hub set up, you can only invite people when you're home and connected to your home Wi-Fi network. Matter-enabled accessories require a home hub, such as Apple TV 4K or HomePod mini.
• If Home has been upgraded to the new Home architecture, you must set up a home hub to share control of your home.
• You and the people you invite need the latest version of iOS, iPadOS, or macOS.
• Make sure that you and the people you invite are signed in to iCloud on iPhone, iPad, or Mac. In iCloud settings, turn on Home.
• Make sure that you and the people you invite haven't blocked each other's phone number or Apple ID. Learn how to manage blocked phone numbers, contacts, and emails on iPhone or iPad and how to manage blocked callers on Mac.

Cheers.

Neil22R,

I am having the same issue and the posted guidance does not fix the problem. Have a HomeHub setup and operating as expected with my account on all devices. All devices updated to most recent releases as of today. Cannot get the invitation to go through to my wife on her iPhone, which is also updated. She is signed into iCloud and is also a member of our family on there.
