Are you talking about sponsor approvals?   Six months is not outrageous to receive your AOR2.   Are you saying that January applicants through Mexico City have already gotten their  PPRs?   That would be some kind of divine miracle.
		
		
	 
No. My sponsor approval was fairly quick.
Here is my timeline :
January 8, 2019 application delivered 
February 27, 2019 application accepted email 
March 26, 2019 requested biometrics 
March 27, 2019 sponsor approved 
March 27, 2019 requested medical exams 
March 29, 2019 submitted medical exams and biometrics 
March 31, 2019 passed medical exam 
The problem is that my file has not even been transferred from Sydney to Mexico yet. People with the same timeline had their applications transferred by April and have approvals as of June/July. I do not know where from. I'm going based on this site's spreadsheet for January 2019 outland application. 
It has been 6 months and I have not received my AOR2 and it has been 4 months since I have received and updates. Last update was medical exam approval March 31
