Why is web tracking not visible in reporting

If you do not see the web tracking option in Reporting, most likely is that the account you are using to access does not have landing page access.

If you are not an organization admin with privileges to modify user accounts, contact your organization admin. If you have the necessary privileges, then go to Settings> User accounts and select the user name that you want to amend permissions. Expand User Permissions and select Landing Pages - Full access. If you don't see the changes, clear the browser's cache or perform a hard refresh.
