i have been having issues when I am making annotations and comments to a PDF file. I don't see any options to save or anything but seems like it automatically updates the file on the cloud. but I've been losing my comments and getting duplicates of the file naming them with "conflicted" and keeps duplicating them and losing the comments. It's making this app absolutely useless and unreliable. What is the point of using if I can't trust acrobat to actually keep my work. extremely disappointed!
