That's exactly why they put these dates on the website. To deter people from arguing with them, while they do whatever they want. I am Nov 2019 applicant, still waiting the oath, while Feb 2021 applicants are getting oath invites. So, yes, they put they are finalizing Aug 2019, but in reality 2019 applicants are ignored, and other much later applicants are being prioritized. Honestly, I was eager and excited to get my Canadian citizenship when I applied, but IRCC has managed to make the experience full of disappointments, frustrations, and anxiety.
