Re: why can't I amend or cancel my campaigns?
Hello and welcome,
why can't I cancel or amend my campaigns
Is it by chance are you referring to Adwords Express campaign here? If yes, then you need to login to this URL http://adwords.google.com/express/ and make the necessary required changes which are allowed.
Otherwise, there might be access level issue. If you have a standard or admin access, then you can make the changes. If you have read only access, you can't.
Hope that helps!
