Download Doesnt work

I have tried for the past 6 hrs to download a book for "offline" use since I want to listen to it on an airplane. The app is useless, doesnt work. The "Tillgänglig offline" is set to "Ja" but it just kick it back to "Nej" and does not complete the download. My internet speed is 20MB/s and should download the book in about 30 sec. Does not work, just wasted 185Kr.

Also, there is no way to create bookmarks???
