I am on the same boat. Been complaining about it in the SF thread just below this one... LOL Have you sent the support team a message about this? I've been meaning to, but I'm a little lazy to type a report from my phone. Though, I'm constantly emailing complaints, so I have the addresses stored...
Well! We can only hope, and it makes me very bitter since I passed Chapter 9 probably over a couple weeks ago and got to the final Charm Level Checkpoint the other day~ <3 Some help that is going to be, getting the prizes in a couple weeks. I was talking with another person, and she got it immediately after passing Chapter 9, but it was after the campaign appeared.
Besides, I do not believe that quote refers to passing certain points - I believe it is about ranking, as it takes time for the system to record aaallllll the people who tie and junk like that. Same as any other event.
