How to delete and recover forms
A saved form can be deleted in the app by swiping left on the form. The Delete button appears. Click it to confirm the deletion. You will have a few seconds to undo your delete if you choose.
Deleted forms are “stored” for five days and can be recovered during that time. Click the More menu, then Deleted Items. Mark the box next to any forms you want to recover and click Restore. The form will return to the Saved/received forms list.
