Rosa has requested that two different support documents be updated for current UX of SimplyE:

Just creating a Jira ticket so this is not lost in my inbox:

Can you please edit as needed - 

Landscape Mode

Landscape Mode is not supported for smartphones in SimplyE. It is supported for tablet devices in SimplyE version 1.0.0.

Fonts Fail to Adjust in Certain E-Books

Certain ePub files are formatted in a way that prohibits the user from changing the font size.

Blank Pages When Advancing Chapters

You may see blank pages after you finish a chapter in the SimplyE app. Please allow your device to load the chapter before advancing to the next page. If this does not solve the issue close the book by selecting My Books and then select Read. 

White Text on Black Background

You may see a book not rendering correctly if the text is set to white and the background to black. Some books in our collection have been formatted to override the user's background selection. This places white text over a white background. The best way to remedy this issue is to avoid using the black background option on this particular e-book.
