Viewing booked seats through Manage my bookings

Booked fab extra legroom seats on our flight to NY next summer through Manage my booking, chuffed , new system worked fast and efficient . However I am not able to view seats now they are booked unlike I did this summer. I know I don't need to see them in front of me but untill the new system came into play I was able to bring the seat map up through manage my booking and see how the flight was booking up . I emailed Virgin and got a reply back within 24 hours and was told now that I have booked and paid for extra legroom seats I was not able to view them . What about if I wanted to change seats ? It seems I would now have to call them . Has anyone else had this message appear when they have gone back to view booked seats using thd new seat booking system that has just come live ?
