Acrobat Comment Tool issue

Apparently they took the option away where you can erase comments etc. on a page or they made it hard to find.  Why they move stuff around is beyond me.  We don't want to have to look for stuff in new places, keep it in the same place for the next 1,000 years.  Can someone please tell me where the Erase a Drawing tool is on the new Adobe Acrobat Pro?  My suggestion is to put all the tools either on one side with them on all the time or the top (preferably top) but not in various different widows to find various different tools.  Have it so you can open and close the tool bar with clicking on one icon, but make it intuitive.  Also, have a key you can open and close.   If it takes more than 5 seconds to figure out anything in a program, it is not intutive in my opinion. 

New Discovery!

Sometimes I replace the same text more than once, so I copy that text. I can highlight the text to replace and do the keystroke for Paste (cmd-P on a Mac) and the replace text tool makes a new comment with the text I just pasted. This function still works, even though I can't just type and have the text replaced.

I'm only confirming this behavior.  I work with the commenting tools in Acrobat all day every day (book production), and this bug has has a dramatic negative affect on my productivity.  I'm hoping it is fixed soon or that we're given the ability to downgrade to a version that works.

New update. I hope it provides the engineers with a clue.

I opened a file this morning and worked with it for a couple of hours. I added several comments, but had no need for the insert or delete tools. When I did need these tools, they worked, but only for a few times before they stopped working again. 

So the issue isn't that having the file open for a while or even commented on for a while. It is those two specific tools that timeout after having used them for a while.

There's another issue that started occuring at the same time as the delete/insert keystrokes stopped working. It's not as annoying, but I thought I'd report it in case it helps in finding the bug.

I create bookmarks for pages in my documents. Before the upgrade, when I dragged a bookmark in the list, I saw a line that showed me where I was moving the bookmark to. After the upgrade, that line no longer appears. I can still drag bookmarks and reorder, but it takes several attempts to get the bookmark where I want it.

@RainbowCollage  Thanks for reporting the issue to us. Since the issue is related to keyboard shortcuts, can we schedule a meeting to understand and debug better. Please share your email ID on which we can send the meeting invite. 

Thanks
