You can actually check to see if one of your partners has access (especially now when we're slammed and it'll take a while for us to answer tickets like this). here's how:
Suppliers are given access to all clients and all campaigns in the seat. they are restricted to their site only. this limits the amount of time we're spending curating access.
Go to CM and Click user profiles on the right rail:
Search for the partner email or part of the email in the search box. it'll bring up a list of accounts.
If you see the email you're looking for in that list, click it to see what they actually have access to. When you're in their account click the filter tab. Every vendor should have read only access (XM-Publisher or Partner Reporting), should have access to all advertisers, to all campaigns, but to only their site, in this case, Discovery.com. That set up allows us to set it and forget it and not have to adjust their access every time a new campaign is running on that site.
Please submit a ticket to AdOps if you don't have access to see all of the things outlined above. You won't be able to change anything, but you should be able to see it.
