I just tested on one of my "normal" user accounts, and that is the behaviour I see too..
I am positive that it used to be that if you had no access to Data Warehouse, then it shouldn't even appear in the menu for you... looks like it's there, but it doesn't load or allow you to do anything.
This doesn't seem like a great user experience to be honest... At least if the option was missing, you would know without a doubt that you didn't have the correct permissions.. this experience just seems like it might be Adobe having a issue, or a network problem on your own local machine.....
