Can't add "account recovery contact" for iPhone iOS 17.5 even though on iMessage
I am using Advanced Data Protection on my iPhone. I'm trying to add my wife as an Account Recovery contact for iCloud on my iPhone 11 Pro, running iOS 17.5.1.
I get an error message that only recoveries on iMessage can be added.
However, my wife has an iPhone and is on iMessage.
What can I do?
iPhone 11 Pro, iOS 17
