Responding to Tasks From Flow
Simple collaboration is what makes Flow such a great task-management application. There are several ways to comment on a task. To comment on a task through the web app, just open your inbox or any list in Flow. Click on a task’s name to open the task’s unique page.
Now, click into the expandable comment field at the bottom of the page.
The comment form will automatically expand when you select it.
You can write your comment, and format your text with Markdown or HTML formatting. You can also attach files to your reply if you want. Once you’re finished, click Post Comment.
