I had issues checking in as well. We had 100% but eDocs would not come through even after a week. I called multiple times and chatted online several times as well, pretty inconsistent responses of "being unable to help at all" to "I fixed it, it should be sending out an email shortly" which never happened. Finally, someone through text was able to resolve the issue and we got our eDocs immediately.
NCL has been pretty inconsistent with training and communication for my check in process which was annoying, seems you might need several attempts before you get ahold of someone who can actually resolve the technical check-in issues.
