V4.5.18 (August 2019?] seems to be vastly improved. I've just realised it's been a while since I hated it, so I've increased my rating from 3 to 4 stars. It's now my favourite ereader, but it's still clunky at times. I had many gripes when I first started using this app, but only minor ones now.There is NO DIRECT SUPPORT option within this app. Help requests are directed to your local library, which is near pointless if you want to report a bug. This might be why it's so buggy. If you want to report bugs, try the contact page of the bibliotheca website.Page syncing across devices is still hit and miss. It's fairly reliable if you close the book on one device and then wait a few seconds before closing the app before opening it on another device. It's worth leaving a bookmark before closing it too.It's the only library ebook app I know of that directly supports copying of text, and you can also highlight text and add notes. Tapping and holding to select text, oddly, often doesn’t work on particular words, especially italic text, and often parts of some words are unselectable. The workaround is to select another word, then drag the selection limits, using the odd but precise crosshairs thing that pops up if you start dragging quickly enough
