Yeah, you can't see your secondary after it is submitted. I already tried to do this before my interview, but I couldn't access the file even with the specific ID and password they require you to do for the secondary.
I also never understand why they did that. It's highly unintuitive and often times, I forget which secondary is the one that I was actually working on last before the save because at one point, I was doing two simultaneously. I think in order to prevent 'confusion' if you are a reapplicant, like I was, was to prevent people from accessing the secondary after submission.
Although, when you think about it, I would think that most reapplicants would notice that they're working on their old secondary not their new one. Again, it's all needlessly confusing. Maybe they'll revamp it someday.
Uh, I hope that answered your question. It kinda turned into a rant
