Time Supervision - Unable to keep and change 10 contacts in Norton Family

Under the old Norton Family website it was possible to have 10 contacts with time supervision.

The new Norton Family website only supports 6 contacts.  After almost 3 hours on chat with the support team the last time I had this problem, they were able to route me to the old website to make the change.

However the link to the old website no longer works, and 6 contacts when the time is out is simply not enough for a child.

Is there any way I can change the contacts while maintaining 10 contacts.

Thanks
