Use subtasks, comments, activity, dependencies, and attachments

Tasks often need more than a name and due date. Subtasks break work into smaller steps, comments keep discussion attached to the Task, Activity records tracked changes, dependencies show blocking/waiting relationships, and attachments keep files with the Task.

These sections keep execution detail, discussion history, files, and dependency context attached to the Task.

Before you start

• You must have access to the Task.
• Subtasks, comments, activity, dependencies, and attachments appear only when enabled in App Settings.
• Creating or editing subtasks requires edit access and subtask availability.
• Commenting requires comment access.
• Uploading and deleting attachments requires attachment access, editability, and online state.
• Removing dependencies requires edit access and dependency availability.

How Task collaboration works

1. Open a Task.
2. Use Overview for main fields.
3. Use Subtasks when the Task needs smaller steps.
4. Use Comments for discussion and decisions.
5. Use Activity to audit changes.
6. Use Dependency when order or blockers matter.
7. Use Attachments for supporting files.

Expected outcome: The Task has the right execution detail and history in one place.

Add subtasks

1. Open the Task.
2. Open the Subtasks section or tab.
3. Enter a clear subtask name.
4. Press Enter or use the create button.
5. Assign, date, or update the subtask when it needs independent tracking.
6. Use Pending/Completed filters to review progress.

Reorder subtasks

1. Open Subtasks.
2. Drag a subtask into the desired order.
3. Wait for the order to save.
4. Use the expand/collapse toggle if card content is taking too much space.

Add or manage comments

1. Open Comments.
2. Type the update, decision, or question.
3. Submit the comment.
4. Use comment more actions to edit or delete your own comment when allowed.
5. Use comments instead of chat when the context should stay attached to this Task.

Review dependencies

1. Open Dependency.
2. Review Blocking and Waiting groups.
3. Open linked Tasks when you need more detail.
4. Remove an incorrect dependency only when you are sure it should no longer be linked.

Upload and manage attachments

1. Open the Task Overview.
2. Find Attachments.
3. Use the upload tile.
4. Wait for upload completion.
5. Open or preview the file card.
6. Delete outdated files from the file more actions menu when allowed.

Troubleshooting

Subtasks are missing or disabled

• Symptom: You cannot see or create subtasks.
• Cause: Subtasks may be disabled, plan-limited, or you may not have edit/create access.
• Resolution:
  1. Check App Settings.
  2. Confirm your edit access.
  3. Ask the Space owner or admin to review plan availability if an upgrade prompt appears.

Comments are not available

• Symptom: The Comments tab, composer, edit action, or delete action is missing.
• Cause: Comments may be disabled, or you may not have comment access. Edit/delete can be limited to your own comments.
• Resolution:
  1. Confirm Comments are enabled.
  2. Ask for comment access if you should participate.
  3. Ask the comment owner or an authorized user to update a comment you cannot manage.

Activity does not show expected changes

• Symptom: You expect a change in Activity, but it is not visible.
• Cause: Activity may be disabled, offline, delayed, filtered to meaningful fields, or missing older entries.
• Resolution:
  1. Refresh after sync completes.
  2. Confirm Activity is enabled.
  3. Add a comment if the missing context is important.

Dependencies are not editable

• Symptom: You can see Blocking or Waiting Tasks but cannot remove a dependency.
• Cause: Dependency edit access may be unavailable.
• Resolution:
  1. Confirm Dependency is enabled.
  2. Ask for edit access if you should manage dependency links.
  3. Ask an authorized user to remove incorrect links.

Attachments do not upload

• Symptom: Upload is hidden, disabled, rejected, or stuck.
• Cause: You may be offline, missing attachment access, using an unsupported file type, exceeding the file size limit, or blocked by plan availability.
• Resolution:
  1. Confirm the connection.
  2. Check attachment access.
  3. Try a smaller supported file.
  4. Refresh the attachment list.
  5. Report the issue with file type and size if it still fails.

FAQ

Should I use comments or chat?

Use comments for updates that should stay attached to the Task. Use chat for broader discussion that is not tied to one Task.

Are subtasks separate Tasks?

Subtasks are Task-like items connected to a parent Task. They can be tracked while keeping the parent organized.

Are attachments available offline?

Attachment listing, upload, and refresh depend on network access. Files already opened by the browser or device may still be available locally, but do not rely on that for shared access.
