Text not appearing in app when mobile device is in Landscape mode (Bloom is source for book)

We are using Reading App Builder (RAB) 4.1.5 to create Reading apps where the books come from Bloom 4.1.15.

The app works normally when in the device is oriented portrait. When the device is oriented landscape, the page’s image is displayed full screen and we do not see any text. If the page does not have an in image, only text, the app presents a black display…as if it is a placeholder for an image. And we do not see any text.

I have created a test Bloom book with different variations of picture + text, but RAB will always put the image on top and will always have the image go full screen.

Is it possible to configure RAB such that a page will show both the image and text when in landscape?
