Navigation Issues

I’m writing to report a navigation issue I’ve encountered in the Bible App, which was built with SAB 11.1. Typically, users can navigate back through the chapters by pressing the phone’s back button. For instance, if I’m reading Psalms chapter 3 and wish to return to Acts chapter 3, which I had previously read, I would simply press the back button. Now the back button is currently malfunctioning; instead of taking me to the previous chapters, it’s directing me straight to the content menu screen. This change has made it difficult to navigate through previously read chapters, causing frustration among users. I kindly request assistance in resolving this issue and would appreciate any insights or suggestions you may have. Thank you for your attention to this matter!

I have observed the same thing. In apps that do not have a Contents Menu, the app goes into the background actually.
I have reported this as a bug to the developers.

Thank you sir. I hope it will be rectified.
