Similar to sending comment notifications, you can send notifications to other users when posting comments on pull requests.
Please note that replying to emails from Backlog regarding the pull requests will not post to the comments section, unlike issues, where replying to emails automatically posts to the comment section.
Comments can also be added to a specific section of code. Click the "Files" tab to show the code changes for each file.
As you hover over a line of code, a “+” button will appear, allowing you to create a comment referencing that specific line. Enter your comment (e.g: “Fix this typo”), select the users who should be notified of your comment, then click the "Submit" button.
