Turns out that only "DC Standard" is part of the Creative Cloud membership. This is silly - Creative Cloud all-apps members pay a high monthly subscription, can't you throw in DC Pro for your most loyal customers? We need to optimize PDFs, it seems silly to pay another $14.99 on top of that. Besides a lot of the same editing is possible in Illustrator.
