When you're reviewing a flow, and you have some comments, a question about the flow, or just like to leave feedback, you can use the Comments feature on your flow canvas.
☝️ The main difference between labels and comments is that labels are used mainly for documentation, but comments are used for feedback, questions, etc.
You can add a comment by pressing Cmd + Clicking (Ctrl for Windows and Linux users) anywhere on the flow canvas or by using the + button on the bottom right of the flow canvas:
The comments on the Flows tab work exactly the same as in the screen detail. You can add visual elements, use Markdown-formatted text, organize them using colors, or so. It's also possible to view/hide comments with the 🐵 button at the bottom right of the flow canvas and filter them by their colors or status (open/mentioned/resolved.)

💁♀️ You can make a comment stick to a screen by creating a comment on the desired screen or by dragging a comment on the flow canvas onto the desired screen.
When to add a comment on a screen vs. a flow?
In Zeplin, you can add comments on either an individual screen or a flow. We'd recommend following this simple principle:
If your question or feedback is about an element or behavior within a screen, then add the comment on the screen, not the flow.
If your question or feedback is about the user journey itself, for example, how a screen connects to another screen, then add the comment on the flow.
