Can not view material – Cengage Mobile Review

I downloaded the help in hopes of accessing the book to read during work. I have downloaded the book 3 times now and still pulls up a white screen every single time. I can access the chapters and descriptions but when it takes me to the book I get a white screen or error message saying book not found. Running the most up to date IOS system. No problem accessing from safari or my laptop but cannot access from the app. Seems like a recurring issue from the developer as previous reviews state the same issue. Update: Took me 5 times to download the book before it finally worked. Not a good first start for the app but will utilize and comment again once class is completed.
