I believe there are other submissions on this topic. I believe this is also a bug. I am delivering bible study using Preaching Mode on my Kindle Fire. When I click on a longer reference, e.g., Ecclesiastes 3: 1-11, I only see the first 6.5 verses in the pop-up. I would like to see all of them. The idea is to make the pop-up content configurable.
Also, I know there is an open button at the bottom to open up the reference in my selected bible. When I click the Open icon, the pop-up disappears and nothing opens.
Interestingly, I tried preaching mode on my iPhone and the links do not bring up the scripture reference in a pop-up. I think that makes sense though.
