Using the latest version of Google Ads Editor can help prevent issues. To download the latest version, visit the Google Ads Editor download page.
If you're using version 10.3.2 or earlier, it isn't possible to post changes to your dynamic search ad website domain. (This setting is located on the Campaigns tab, in the "Dynamic search ad asset" panel.) If you attempt to post a campaign with this change, the post fails. To complete the post, revert the change and then retry the post. Then, to update your dynamic search ad website domain, you can either download the latest version of Google Ads Editor or sign in to your Google Ads account.
