Wi-fi passwords are not being synced over iCloud

Hi!

After updating my gear to iOS 18.0.1, iPadOS 18.0.1 and macOS 15.0.1, I noticed that all passwords are being synced as expected, but the wi-fi passwords not.

Each of my devices has different wi-fi SSIDs stored, that are not synced across them.

I already tried disabling and re-enabling iCloud Passwords and Keychain syncing on all devices, but although the other password entries are being synced, the wi-fi are not.

Anyone noticed the same issue?
