How to unpublish a form
If you need to make a change to a form you may want to unpublish it while making the changes. Or if you no longer are using a form, you could unpublish it rather than delete it just in case you think you may need the form at a later time. By unpublishing, it will no longer be available to download to devices, essentially disabling the form, allowing time to make a final decision about its use before deleting.
The forms with the empty icon next to its name in the Form and Report Designer menu are unpublished and do not appear on a user's device.
TIP: When adding or changing a workflow, you may want to unpublish the form until your workflow setup is complete.
When unpublishing a form version, check all areas of the form to ensure the report, data maps, child forms, workflows etc. are not affected.
