Hi,
I also applied for Citizenship on Oct 2020 and received AOR in Jan 2021. It's already 25 months still I received my AOR. My application has exceeded normal processing times at this moment (23 months) . Until now only Citizenship Test and Background verification shows completed status. Rest of the steps are still in progress. I haves submitted an webform enquiry 3 weeks back and has not received any answers. I also called on the IRCC contact number and after weeks of call not being transferred to an agent finally I cloud talk to an agent. She could at least confirm me that the application is still under process and not pending for any action on myside. I simply need to wait and keep an eye on my email. Also one more thing to mention is... Even though on my application status page, there is no update since Jul 2021 (Test result), I can see on the top left corner of the page mentioned "Updated in Dec 2022". which means something is updated in my application but in the background or some officer just had a look at it... never know.
Hope others have better luck!
Cheers!
