Hey citizen of the world.
When you reopened the link from your personal email saying your information was saved it should of opened and continued on with your last question done. I also didn’t receive an email saying that the questionnaires was completed but a simple thank you after clicking submit.
so I again saved it and opened again from my personal email then taking me through the questions I completed and clicked submit. I hope this helped you with any direction on the status of your application.
