Comment status can be seen in the Documents area to the far right of an item's row. If there is a new comment that you haven’t seen, you will see a red comment bubble. If there are existing comments, all of which you have seen, you will see a gray bubble. Click the bubble to view the Comments section for the item.

In the Documents area, click on the 3 vertical dots ( ︙ ) to the right of an item's row. Click View comments/details.

Click in the Add a comment box and enter your new comment. If you'd like to send users notification of the comment you're adding, you can use the + icon to subscribe new users to any future comments on the current document.

Alternatively, you can also Mention a User to send just the current comment. Click the  Send button to save your comment.   

Please note that once posted, comments cannot be edited.

A user can delete or edit their own comments, and an Administrator can delete comments made by any user (but can only edit comments they made). Click the trash can icon to the right of the comment you wish to delete, or the pencil icon to edit. Click OK to confirm the delete, or Save to confirm the edit.

Even if a comment is deleted, a record of the comment remains in the system activity logs and can be accessed by an administrator on the Activity logs report under the USAGE section in the Reports area.

To react to a comment, click the smiley face emoji icon.

To reply to any existing comment, including your own, click the "Reply in thread" arrow icon found when the cursor hovers overs on an existing comment. Replying provides a means of indenting comments that are intended to serve as a response to an existing comment.
