Cannot add a user to Home in iOS 16.3

Hello Clinker325,

We understand that you've tried several thing in order to share control of your accessories using the Home app. To ensure that we're covering all of our bases, we suggest checking out the following steps as well:

• "If you can no longer connect to a home, or receive or accept a home invitation, learn what to do.
• 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."
