Some have received, some haven't. There is hardly any consensus on why this is so.
In terms of contents, the 2nd AOR explicitly states that the application is evaluated and found to be complete unlike the 1st AOR (eAPR) which merely confirms receipt of online transfer of the application.
There are multiple instances of people successfully using eAPR for BOWP purposes but, of late, CIC seems to have mandated that one has to wait for and apply with the 2nd AOR.
Hope this helps.
