As of now, after a promote campaign is active, user does not have the ability to edit/or make changes to the campaign. It would be a game changer if we could make tweaks/edits without having to create an entirely new campaign. A new campaign's data always start back at 0 and that sucks!
Thank you for reaching out with your suggestion.
We completely agree that having the ability to edit an active campaign would add significant value to the new Promote feature. You'll be pleased to know that this is something we are actively investigating and hope to implement in the future.
Thank you again for your feedback—it’s greatly appreciated!
