This is brilliant information
@maddy4u123, guys not only does this explains PPRs not being issued for completed files.
This also explains the changes in trends for FSWO and CEC. As only CEC and Inland and US candidates are supposed to send PP to Ottawa, hence CIC delayed their processing in order to clear backlog of PP to be stamped. Whereas FSWO send PP to LVOs hence no issue there of any PP backlog, hence faster processing and priority to FSWO and delay in CEC. As the fast CEC PPRs in previous months must have created huge rush of PP at Ottawa. Also clearly they have high shortage of workforce, hire me CIC

.
Though again this my perspective, anyone with similar conclusion or some insight?
