I'm utterly disappointed. The problem got solved for a while after I reinstalled. But it came back. I had to do it again on which I have lost the highlighted version of my pdf book. It does not make any sense as it was saved in the document cloud. It took me a lot of effort! What should I do now? Should I read something, highlight it and lose it all again? Or should I uninstall it for good. I don't know what to say. I used to love this app.
