Help With CC, Moon+ Reader Pro Android 6.01

I am using CC Version 5.1.1.3 (327) and Moon+ Reader Pro 3.4.7.

My device is SM-G935F running Android version 6.01.

Question: What can I do to make Moon+ Reader open the book I have selected in CC Book Details screen when I tap on Read?

I just upgraded my device from Samsung S4 to Samsung S7 Edge.

I store my CC library books on an SD Card. I transferred the SD card from the S4 to the S7E.

I successfully have Run Calibre and Calibre Companion to sync books on the S7E.

I use Moon+ Reader Pro. On the S4, I was able to navigate to the Book Details screen in CC then click Read and Moon+ Reader would open the book and I could start reading.

On the S7E, when I click Read in the Book Details screen, Moon+ Reader opens but does not open the book for reading. It opens the last book read or opens to the Recent List in Moon+ Reader.
