Reading from my phone

When logging onto this app from my phone it tells me to open the boom from a desktop first. When I do that I am still unable to read my books from my phone. This has happened with my current and last class. This needs to be fixed. I used to be able to read while I am at work. When I log onto bookshelf from my desktop I see all my books. But from the app there are 2 books missing. This is very frustrating.
