Hi all - I posted last week with my situation (what to do when you get copr) and just wanted to give an update as I now (think) I have my head around it.
I received COPR (confirmation of PR) with the final steps being post x2 passport pictures to the London office and upload a passport scan and updated information chart in my CIC (this is the action I take as I'm British and Visa Exempt).
When I went to upload the scans into CIC there was no option to do so and I'd already posted the docs so was stuck! You only have the option to upload when there is a request in CIC and there isn't one. Someone on the forum very kindly gave advice and I raise a technical issue on my CIC, and still waiting for an update. You only have 30 days to do this and I'm about 15 in, so i'm slightly worried but hopefully all will be ok - fingers crossed!!
I will update when I have more info, hopefully this will be of use if someone else ever has this issue.
