I'm a professional editor and writer, and therefore a frequent user of the comments function. I concur with many of these negative comments and have also found the update has seriously disrupted my workflow (I have been using it since April 29). The new functionalities do not improve my work experience in any way. The comment function is rarely used collaboratively in my work, and the times it did, the "reply" function worked fine. Of most concern is the extra space any Word document with comments now takes up onscreen, as I am often working with references and templates beside the active document (and I work on a large screen, I can't imagine trying to work on a laptop). The additional clicks and mousing required to enter, edit or delete comments also add up to a great deal more time and unnecessary interruptions. Please provide users with a way to revert to classic comments, which worked beautifully.
