After going through the process of logging in to twitch to allow the app to access my account, I clicked several books to download: The Sunless Citadel, the PHB, the DMG and the MM.
Each one was added to my list of files being downloaded correctly. However, upon selecting to download the MM I was immediately taken to the authentication screen and asked to allow the app again. I clicked allow, and this reopened the app and downloaded the manifest.json file again (which was slow because it was one of many files being downloaded). When the app opened, the books were still being downloaded but they weren't showing as "in-progress" in the UI. I clicked to download the PHB again and it was again added to the list of files being downloaded, so that it appears twice in that list now. I clicked the DMG and the same thing happened (though I noticed it spent some time as <Untitled> in the downloads list before changing to dmg). Then I clicked the MM again and it again took me to the authentication screen as it did before.
For whatever reason, my list of files in progress downloading is now: phb phb dmg <Untitled> mm dmg Not the order that I selected them in, and there is no second MM (the Untitled entry became manifest.json just now).
UPDATE:
After the downloads completed, the app was open but did not register that any of them were available. Instead it asked to download the PHB again when I clicked it. I will leave it to one book at a time for now and see if that works.
I just installed on Android 5.0.2
