Revert Imports from Google Ads
There should be an option, like with other changes in Change History, to be able to revert imported Google Ads campaigns, ad groups, etc. If something is mistakenly imported incorrectly or accidentally, there is no way to revert the changes that were made. This can be very time-intensive to correct under the current setup.

In the tree view, select the account, campaign or ad group containing the changes to revert.
Select the appropriate type from the type list (for example, to revert a keyword edit, select Keywords).
Right-click the rows containing the changes to revert and click Revert.
