Android 15 - Cannot set default password app

We use Microsoft Intune to manage devices. For the devices which have upgraded to Android 15, the end users can no longer select Microsoft Authenticator as their default application for auto filling passwords. I cannot find any settings in Intune to allow it. All devices are fully managed corporate owned devices. The devices are all Google Pixel 8 or 8a devices. 

Is this a bug in 15 or am I missing something?
