To edit an existing campaign:
Click on the Campaigns button.
On the Campaigns page, click on the Campaign you want to edit and click the Edit button. The Edit Campaign page opens. You can edit the campaign type, campaign settings and how you will share the campaign. You can then save & deploy your changes.
Note: You can’t edit a contest campaign until the voting period has ended. You can open the editor for the purpose of obtaining deploy code & link during this period, but any edits you make will not be saved.
