Some people got their OWP in around 3 months from date app is received, others just recently took over 5 months.
Once you get AOR in around 2 months, then you will be asked to link the app to an online account and submit schedule A and PCC. After that the med request should be the next step but expect no movement on that for many months, for example June 2017 applicants still haven't had medical requests yet.
Pretty much expect complete silence for months on end, you have a wait until the AOR, then an even longer wait after that, most of the movement on the app seems to be done towards the end of the 12-14 month process.
