Same case here, the system is indicating that the "Personal Details" section is "still in progress" for both my wife and my son. Curiously, my own section shows as complete.
I have attempted to resolve this by using the "Check for completeness" feature, but it does not provide any feedback or indication of missing information. I have also reviewed each field multiple times to ensure all necessary data is entered correctly, but the issue persists.
This situation is preventing me from progressing further with the application process
