HomeKit sharing not working

After some more troubleshooting I discovered that the issue here lies within the home hubs. It appears that the user data isn’t synced correctly with the upgrade.

To resolve the issue

1. Unplug all home hubs in your Home
2. Restart your devices
3. Plug in only one home hub and wait for it to become connected in the Home app
4. Remove anyone who had issues accepting the invite if their broken profile persists in your Home
5. Send new invites
6. Once they have joined, you can connect the remaining hubs, the new data will propagate to the others as they come online

This worked for me, but it may not for everyone. Let me know if this helps.

I am having no end of problems adding people. I have reset the home app, unplugged everything then added one HomePod and still nothing works. Both people have updated their phones to the latest and all software on the HomePods are up to date…… nothing is working. Anyone got any ideas?

Wait for a software update from Apple.

Anyone who is still having this issue needs to wait until Apple fixes this issue, most likely with another iOS update. This is what Apple recently announced at Upgrade to the new Home architecture - Apple Support

"We temporarily removed the option to upgrade to the new Home architecture. The option to upgrade will return soon. If you already upgraded, you are unaffected by this change."

The advise from Devisevib worked for me. Appears all of the home hubs (including HomePad and Apple TVs) need to be manually rebooted in order to sync correctly after the iOS 16.2 update.

This is what I did that worked for me:

1. Unplug all Home hubs (including HomePods and Apple TVs) in your Home. Don't unplug any other Home Accessories (don't unplug smart switches, locks, etc.)
2. Plug in only one Home hub (in my case, I plugged in a HomePod) and wait for the hub to become reconnected in the Home app. This happens automatically.
3. Check to see if you need to remove anyone who had issues accepting the original invite (in my case, there wasn't any original invitation to remove)
4. Send a new invite from your Home app to the other person
5. Once the other person has accepted your invite, you can plug in the remaining hubs. The new data propagated to the other person who accepted my invite.
6. Done

Same exact issue here. I am going to reach out to Apple Support. Tried everything I could. But I also will not be happy if it means deleting and recreating my Home. Simply too many accessories to reconfigure and automate again.

have the same issue here. But I did not delete my wife in HomeKit. She noticed it when she was about to turn off some lights. And then I went in to the HK app. And I was alone in my HK home
