Books keep disappearing

I am a special education teacher for a middle school where I work with students who have varied levels of reading disabilities. We downloaded this app on several of our devices in order to make reading material more accessible to students. However, the books keep disappearing. Students will go to open the application on their tablet to find that their books are all gone. I understand that it is simple to read download the book. That is not the difficult part. After I get the book downloaded, I have to investigate what page they were on and where they were at in that page. When this happens, it tends to take the majority of the class. Leaving no time for actual reading. Then, add another 12 students on top of that. Lastly, not all books are separated by page numbers. They are simply a long scroll divided by any type of subdivision the book has naturally put in place. This increases the level of difficulty to support students in finding where they are act in their reading. Please fix! I had one student who had an entire queue of books that she wanted to read. That list is gone and she is devastated. It breaks my heart to see a child who wants hated to read now so sad that the book she was excited to read are gone. And she is struggling to remember the titles. I would like to continue to use this app but will be forced to look for alternatives if these problems are not resolved.
