I also had a successful result. I had my password issued in December, and I logged in this month, 15 days before my 90 days renewal was due.
I filled in the required information and emailed in about 10am. Received an instant email acknowledgment.
Approval email with attached slip for stapling into my passport was received by email about 4pm that same afternoon.
Note that the new 90 days started on the expiry date of my previous due date, so there was no disadvantage in applying 15 days early.
Also some information is no longer required, such as flight number of arrival aircraft or arrival card number.
