Received the following email from CIC if this help:
December 2, 2016
This letter is addressed to candidates who have been invited to apply for permanent residence to inform them of the steps to follow to avoid technical difficulties when paying the fees for their permanent residence application.
Recent changes to the Express Entry system took place on November 19, 2016. While your application is not affected by these changes, the recent update may be causing problems with paying the application fee and submitting your application on time.
Immigration, Refugees and Citizenship Canada (IRCC) is giving you fifteen (15) more days from the date in your invitation letter to follow the steps below and submit your application. This will make sure you have more time to successfully submit your application for permanent residence.
To ensure that your application is submitted without difficulties, you need to confirm that you provided all the information for your education history and personal activities. To do this, follow these steps:
1. In your profile, go to each web form and open the subsection that includes a grid of saved records. Scroll to the bottom of the section and click the Modify button on a grid entry.
2. Your profile will display your previously entered information. To validate that you have provided all the necessary information, please click the blue Check for Completeness button at the top of the web form.
3. When you have provided the necessary information and are ready to save, click the blue Save and exit button.
4. Repeat these steps for each grid entry in the section.
