Comment length

Workspace comment inputs limit comments to 1,200 characters. For longer feedback, write the summary in a comment and link to a separate page.

Troubleshooting

If you cannot see comment controls, confirm that you are signed in and have comment access.
If reactions do not work, read the toast or message. In read-only mode, Workspace can show Reactions are disabled in read-only mode.
If a copied comment link does not open for someone else, confirm they still have access to the page.
If a comment does not appear immediately, wait for sync or use Force Sync from the page options menu.
