I got some new notes. It shows my MP's office has been asking about my case a couple of times since my email.
They reached out IRCC on Aug.16th, got a reply "... Provided response to Status Enquiry (action needed). requested clarification of timeframe of COPR for approved applicants. NSH4698"
On Aug 24th, there is a new note - "... Provided response to Status Enquiry (no action). left vmail advising MP's assistant that an IC was sent 16 Aug 2021 (Ticket xxxxxx) by a Program Officer (NSH), and a response is still awaited. MD4700"
On Aug 27th, another note - "... Provided response to Status Enquiry (action needed). 2nd request sent on 27Aug2021. NSH4698"
Not sure what IC is but seems like they created ticket to clarify timeframe for COPR.
