As I've said in another comment, I don't actually see that anywhere in Apple's documentation. What they say in [1] is: > Keychain items are transferred from device to device, traveling through Apple servers, but are encrypted end-to-end so that Apple and other devices can’t read their contents. "Contents" is a bit vague (I wish they'd be more precise too), but it doesn't scream "data and metadata to me" – they might well mean that usernames, public keys, domains etc. are accessible to them, and only passwords and private keys are end-to-end encrypted. That would explain your observations. [1] https://support.apple.com/en-us/guide/security/sec1c89c6f3b/web https://support.apple.com/en-us/guide/security/sec1c89c6f3b/...
