Full Screen Problem: the white bar

I am an avid user of the android Gospel Library app and I notice almost every change as I update to the latest versions of the app. I love everything so far. I am, however, getting a white bar on the bottom of the screen when I enter full screen mode. It is the same size as the bottom toolbar and gives me only half of the desired full screen view. I would appreciate a fix, it worked fine before the most recent update. Thank you for all your hard work!

Here's a screenshot.

Same problem here

OK looks good now with latest update. I am way impressed! Starting to catch up with Apple's Gospel Library app.....
