title: How can I review comment history on Azure DevOps Pull Requests?
body: <p>I have noticed that when you modify a comment in a Pull Request, there doesn't seem to be a way to view the history of the comment. As well, comments still allow editing after someone responds to it. One of my colleges is editing comments after he gets a response and our pull requests are not making sense because of it. Is there a history or a way to prevent changes?</p>
