Did you submit your application and visit migri in consecutive days?
Also it's been a while since I submitted my application so I might have forgotten, but when did you pay for your application? I don't remember if you can pay at the service point or not, but if you paid on the day that you proved your identity, my guess is that your application officially entered the system at the time you pay for your application, and get initiallized on the day that you prove your identity. I personally wouldn't worry so much about getting/ not getting automatic email. It is set up in the system so if you get/not get automatic email, it still means that no one has looked at your application.
No, it was 15.08 that I got that automatic email. Nothing else since then. Looks like since 2021, the earliest someone has gotten decision was 7,5 months.
I hope Migri will do something about the backlog, since using covid as an excuse is getting lame. If the government plans to open the country by October, how will migri deals with coming foreign workers and student.
