Help with IT blocking Adobe Cloud use

My IT department gets very protective about cloud platforms. When we first signed up for Adobe Cloud, the only way we were able to get them to license us was for all of our design team to sign a waiver that we would only use the software, we wouldn't use any cloud aspects of the system. Since signing up 7+ years ago, we have moved a lot of our systems to the cloud, and we recently rolled out a new brand and are seeking a release of the block they have on us for the cloud aspects of our account.

IT claims that we do not have admin for the cloud aspects of our account, but I believe that to be incorrect. Everything I have researched online shows that there is an admin console and even admin user roles which allow levels of control over the content on the cloud. (They are essentially saying that if someone were to leave the company, we would lose access to what they had stored on their account on the cloud.)

Opening up cloud collaboration would make it 1000 times easier to collaborate across teams, and manage the new brand assets (logos, colors, templates, style guides, etc). 

Does anyone have any tips on how to get IT to relinquish their hold on us around the cloud aspects of Creative Cloud? I have downloaded several resources, but I am open to others who may have experienced similar issues.
