I've tried all of the attempted fixes above - Linking/Unlinking, uninstalling and trying the PS4 version, changing user accounts and nothing.
I have not been able to restore my initial account with the DD progress, and edition stubs/packs.
Furthermore, I tried to play the new DD from scratch and even if I started over, I was not granted any of the packs or stubs from the edition.
Any more thoughts? I'm thinking of just going the refund route at this point.
