If you would like to delete several proofs that you own at once, you can do this on your dashboard.
To delete multiple proofs
On your dashboard, click the cog icon.
Select which proofs you’d like to delete by marking them with a tick. You will only be able to tick proofs that you own.
Important to note:
The proof and all its versions and comments will be deleted, along with all history.
You can not undo this action, so please be certain for each proof you select to delete.
Select delete, and then yes, delete.
