You can easily revert changes that you make to items in Microsoft Bing Ads Editor. Changes do not become active until you post them to your online Bing Ads account.
The selected items will be restored to the properties or values that they had before you made the changes.
Any changes you've made in Bing Ads Editor since the last time you synced with Bing Ads will be deleted.
You must select the items in the Manager pane with changes that you want to undo before you click Revert; otherwise, the changes that you made will not revert.
