I linked my application on July 6th, got AOR on July 8th. I did not receive the PCC request yet. I uploaded PCC on July 7th using the Application number via webform, IRCC agent confirmed they received it and forwarded it to the related office. Today, I got an email saying that I "To continue processing your application, you must link your application to an online account." even though I linked it before AOR. I called IRCC to see what's going on, Agent confirmed my application is not yet linked!! So I created a new GCKey account and linked my application using the same info. PCC request was there since July 7th and there was an option to upload it!! Has anyone experienced issues like this?
