I created a book in iBooks Author using the Photo Book template. When I rotate to portrait orientation, the photo or widget disappears and a table of contents appears with only the interactive media showing.

Thanx for the prompt response, KT. I have indeed seen that thread, only just after I posted the question.

I have spent hours on the phone with what I now know is a call center in Texas on this question.

I think Apple could be a little more "hands on" with iBooks Author users, and it should also be pointed out that landscape photos will not display in portrait mode.

In my case, I used gallery widgets to display vertical photos, since they look better in portrait mode.

But instead of simply rotating, the page disappears and a TOC of interactive media appears. The gallery behaves as expected when tapped. This is not what I expected, but since the gallery works, I can live with it.

Right now I have "tickets" telling me to "fix" this "problem or to disable portrait mode.

I don't want to disable portrait mode.

Will Apple accept the books if I tell them this is not an "error?"
