How do I get books downloaded in Kindle, Libby, or other storefront/library apps to show up in the main library screen that my Nova Pro defaults to on boot? I'd love to be able to read these books in the default reading app. The Kindle app is fine once you're in to a book but a flashing mess getting there because of the graphics even after optimizing. Libby is even worse with flashing and slow, sometimes unresponsive page turns even after optimizing. It was nearly unusable before optimizing.
I tried configuring library settings to scan all storage and then refreshed the library. Nothing showed. I went to storage and tried to find where the books are kept for both programs but it looks like maybe they have DRM or are encrypted somehow? Maybe this won't be possible without running them through calibre and transferring them back as regular books. Doing that defeats the purpose of buying an android ereader though. If I wanted to run everything I read through Calibre and sideload I would have just stuck to my kindle and not spent the money on this.
If there's no solution without extra transfers involved, has anyone had any luck optimizing Libby? I tried a few variations of animation timeouts, regal refresh, A2 (which doesn't work well when graphics are involved), contrast, etc. The flashing at opening in both Libby and Kindle is enough to make me have to look away from the device for a minute or so while the software loads.
