Recent Calls & Favourites not Syncing alongside only partial/old contacts showing - pls help

[AF172MY2023]

Hello

I was wondering if anyone can help with what is an extreme frustrating problem pls.

I have a new 2023 MY on company car lease
I’m primary account holder and the lease company added my wife as a secondary driver to the car
I have a iPhone 12 Pro and a Gmail account
My Wife has a iPhone 11 & a Hotmail account
Both phones have been successfully setup with Car Key
My Phone has been successfully Sync’d and I can see all contacts, calls made & favourites.
My Wife’s Phone has been partially Sync’d. She sees 6 x very old & random contacts yet NO favourites nor made or received calls

I’ve gone through every “process of elimination step” possible including:
Unpairing and removing all devices
Re-joining each phone in isolation
Reset the the MY Bluetooth settings via the 2 x button reset process
Removed my wife mail account and gone through the above steps
Setup my wife on another iPhone (iPhone 8) – with no success

Even more strange, yet promising, is that I successfully sync’d my daughters iPhone X (who has an Outlook account) & she COULD see all contacts, calls made & favourites

Any help, or similar pain, out there and potential solution/suggestions would be greatly appreciated.

Do her contact appear in the phone's contacts app?
When you first pair, both in the car and on the phone, there are options to allow contacts to be synced, were they enabled?

Hello. Yes to both questions - although only 6 contacts flash up on the Tesla screen and no made/received calls log, nor favourites. Very odd - & frustrating!!
