Where are the footnotes?

The app works fine with questions and answers, and the quizzes, etc. HOWEVER, you have the little footnotes in the text, but they don’t link to the scripture verses. That would be nice if they worked. THANKS.
Hurray- they did it! Wonderful addition of the scripture proof texts. They work very well. Thank you!!
