iCloud Keychain wont sync because previous devices were on old OS versions

[RumorConsumer]

My friend had a MacBook Pro on 10.11 and an iPhone on iOS 15.

She just got a MacBook Air M2 and we installed macOS 13 on it.

Everything works except the keychain from the old devices wont sync over. I signed out of iCloud on the new one, signed back in. Same thing.

I just updated the MacBook Pro to Ventura. Still not working. Now updating the phone to iOS 16.

If this doesn't work, anybody know how to push the keychain into the cloud so it pushes onto the new machine?

Once the phone updates Im going to see if the phone and the old Mac still agree on the sync.

Any ideas welcome.

I am facing a similar issue, but don't know what's causing it. I have also contacted Apple Support on the phone, but they were unable to offer an acceptable solution...

I have three devices on my iCloud account. An iMac, a MacBook, and an iPhone. All devices are on updated software, the iPhone is on the latest iOS, the MacBook is on Catalina, while the older iMac is on High Sierra, since that's the latest supported version.

I am facing an issue with iCloud keychain syncing to the iPhone, which is absurd. I would expect iCloud issues with the older device (the iMac on High Sierra), but iCloud syncing works perfectly between the iMac and the MacBook. However, not on the iPhone. Whenever I create a new password for a website or any other service on the MacBook, it gets transferred over to the iMac; but not to the iPhone.

EVERYTHING else iCloud seems to be working fine on the iPhone. Notes, Calendars, Contacts, messages, everything else syncs just fine between ALL devices. Keychain passwords do not.

I have tried numerous tricks, disabling / enabling Keychain sync from iCloud settings on the iPhone, even completely disconnecting the iPhone from my iCloud account and reconnecting again. Nothing seems to be working.

Apple Support could provide no real solution, they insist that I should first update the MacBook to Monterey (since it's updatable) and then take it from there. This is not an acceptable solution, since the device that's been facing the issues is clearly the iOS device and not the Macs.

Any ideas?

I still havent resolved my friend's issue. I ended up turning iCloud Keychain off everywhere and then tried to enable one by one. Did not work which is puzzling because that should really do it.
