thanks alot buddy for the infoMiddle of 2020 was bad for paper documents sent to IRCC offices. I saw in another thread an interview where an IRCC spokesperson said they couldn’t physically send people into mail rooms to process paper documents.
Photos submitted around that time are quite likely still lingering somewhere in a huge pile of documents.
The situation improved later in the year. I’m reading later CoPR (from Oct/Nov) receiving their PR cards already. It seems to be ‘last in first out’ with IRCC.
