For no apparent reason, it keeps getting stuck on one particular book. I can no longer save ebooks to the attachment folder and thus put them on shelves as of this morning. I have no idea why this has happened or how to fix it. I have tried relaunching it, and I rebooted the phone (Moto G Stylus) twice. It has been suggested that I use a different reader, but how would I download the correct covers, or make use of mobi, djvu, and azw3 files, although I definitely prefer epub and pdf?
