This online version of adobe acrobat genuinely sucks. I just spent like two hours reading and annotating something assigned for a class and I went to try and make a comment on something I highlighted and it stopped working, and I kept pressing wait when I was getting the page unresponsive pop up and it just never fixed itself and so I had to reload the page and I lost all of my annotations and comments. PLEASE FIX THIS ONLINE VERSION OF ADOBE BECAUSE I DO NOT HAVE TIME TO HAVE MISHAPS LIKE THIS AS A COLLEGE STUDENT!
