@Ina1997 Welcome. I know the feeling because like you we are all anxious as well. Based on what I have read in multiple groups I can share the following with you:
1. The time one applied doesn't influence the time an AOR will be issued. like you mentioned AOR and processing seems to be very random so persons just have to wait until they are selected.
2. I suggest you try and see if you are able to link you TR to PR application in your GC account. There were many people who did not receive an AOR and were able to link their TR to PR application in their GC account where they saw several request for documents waiting for their response. Because at time the IRCC I think either forget to send out the AOR or some system error
I hope these helps
