Keeps on hanging

This is a great app which I have been using for several years now. However, the app has been recently hanging / crashing like every 10 minutes and you have to restart each time. I've purchased this app before plus some other add-on features, but it seems that the frequent crashing will somehow manipulate you into getting the PDF expert pro subscription.😒

Bring back annotation as default

Used to be good. Had to deal constantly with the unwanted prompt to avail a premium account, but the final straw was the inconvenience brought by the latest update: you can’t annotate PDFs anymore unless you manually go to Tools -> Annotate -> select file. As a student who has too many PDFs open at a time, this sure is inconvenient. I personally preferred when I could annotate each file without having to go through all that trouble. This i unless I must have messed up settings somewhere, but this only came about after an update. But seeing that there were no settings regarding this, it may seem that the update was to blame. Please bring back annotation as a deafult when opening files, thank you.

Random App crash and Random Scrolling up
02/10/2019
Jethro Lemuel
The app always crashes when I open 3 books at the same time. I am a medical student and I often use multiple books in my study seesions. I hope you will have a fix to this one. Also, at sometime, while I am annotating my books, the app randomly scrolls the whole pdf file up to the first page even though I did not tell the app to do so. It became an annoyance at some point. Please fix.Also, a suggestion, Make it a feature that the apple pencil will be focused more in annotating tools and the finger of the user will be dedicated tfor scrolling. It would be great.
