They finally got back to me. Turns out the attorney did decline it because she thought it's another OINP invitation. Guess one DP is that even after declining the portal still will change the status to "Approved". The attorney told me she has sent an email to OINP to request re-issue of nomination. Not sure how it would go.I would be suspecting too because there is no button to decline/accept an invitation to apply OINP, they only send a notification on EE saying you can either apply or ignore their invitation. The accept/decline button only shows up for the actual nomination on EE profile.
