Home Kit / App Invitation Issue
My husband sends me an invite to join his Home kit on the Home App, but no invitation appears on my Home app. We've tried pretty much everything and can't figure it out.
His phone: iphone 7, My phone: iphone 6s plus
Phones are both updated
Uninstalled and reinstalled Home app
Toggled Keychain on both phones,
Cancelled and resent invitations over a dozen times
I switched my apple ID from "@me" to "@icloud"
Turned off Home on icloud settings, and tried the app to turn it on there... still nothing
Turned off Two step authentification, and nothing... so turned it back on
Tried adding him myself, and it says that his email is not registered with icloud even though it is
He's using a hotmail account, but that shouldn't be a factor if its registered with icloud.
Also "Home" app doesn't appear in both our Settings. It only appears in icloud settings, is that normal?
What other options are there? Would appreciate all the help!
iPhone 6s Plus, iOS 11.2
