If you can see a task, you can comment on it — whether it’s yours, one you’ve created, or one in your organisation that’s relevant to you.
Open the task by tapping on it. Beneath the task information, you’ll find the Add comment button. Once your comment is posted, you can edit it by selecting Edit under the comment, or remove it entirely using Delete.
Every update — adding, editing, or deleting — is recorded in the task activity log at the bottom of the task, so there’s always a clear record of what’s been shared.
