That's my usual manual route (change 3.0 by 2.0 in opf and remove NAV). This time, without removing, I've seen that. So, I wanted to know if there is an automatic way to keep in 3 (or an automatic way to downgrade to 2 in the same way that there is an automatic way to upgrade to 3
)
Please, keep away defenders of EPUB3, people saying that you can ignore the errors and so on. No theological discussion, please
