WHY THIS UPDATE ?!

Omg i cannot believe what you did to this amazing app ! This is garbage now, I cant work with it no more ! Im a student and I told everyone around me to download your app because I thought it was great (and free !) but now I cant highlight a single passage in my PDFs ! This is becoming so difficult to do my projects researches ! Please fix it fast so I can work on it again and highlight passages from my PDFs !!! What have you done ....
