Just for anyone who might encounter this:
I tried taking the test on the first day of the time window, couldn't log in to the test link with my application# and UCI, I'd get to a webpage saying "our records indicate you have not been invited for the citizenship test".
This persisted until 2 days into the window, I emailed Ottawa's office who recommended contacting technical support (their email address is at the bottom of the test invite pdf). Tech support acknowledged a technical issue and suggested to try the next day, and it eventually worked then.
