Orientation in the ePub

I created a sign language book in 16:9 Landscape orientation. When I publish in Bloom Reader, it works ok, but when I try to publish in ePub, it automatically change the orientation to portrait orientation, and the page layout will change. Looking at the preview, video seem to work.

Is there way to publish a sign language book of 16:9 landscape in ePub?

Thank you!

Currently Bloom does not have an option for creating ePUBs in landscape orientation. We apologize for this limitation.
