Why does my reporting area does not show reporting for web tracking or landing pages

Landing page and web tracking reporting are tied to the user permission, Landing Pages - full access.

In order to allow or remove Landing Pages Full access, go to Settings > User Accounts > click the user account and the 'Landing Pages - full access' option is available under the User Permissions section. Organization Admins with Landing Page Full Access unchecked are not able to access the reporting that is related to Landing Page Sites in Reports > Reporting.
