I m in the same boat.But my background Chek went from in progress to NA and to we are processing your background check without medical.
The bgc went from complete NA1,IP1,NA2 to IP2 in more than a week but ME is not cleared. The only explanation is, IRCC started my process without ME which makes senses because I’m CEC inland. It processes faster. By the time my ME cleared would be almost a month, and all my CEC friends got ppr a month after. So even if I am waiting for ME, I still expect my timeline to be the same as my friends. Also, we work at Canadian banks. And came here 18 years old university, no travel history, easiest CEC lol
My BG changed to IP2 stage but I have not passed medicals yet and I m CEC Inland as well.
