I have uploaded a sample customer data file from Profiles and Audiences. The file has been successfully uploaded with 8 data as shown in the graph in Profile and Audiences.
However I do not see the data in Audience Manager and neither the traits or segments created on these data sources return any value. The Profile and Audiences show "Collecting Data". It has been 1 day since the activity has been done.
If you've uploaded data in the Profiles and Audiences interface, it should show in your AAM instance. The Marketing Cloud UI is essentially a skin for Audience Manager. I wonder if there might be an issue with the provisioning for your account. Can you send me a private message with your AAM subdomain or PID and your Marketing Cloud IMS org ID or name? I want to look up your account and ensure everything is linked appropriately. If you could also send me the name of the audience where you uploaded the data, I can check to see if I can see it inside your AAM instance.
Sorry, my explanation was unclear. Anything done inside of the Audience Library interface will show up in the AAM interface. The Customer Attributes interface is separate from AAM. When data is uploaded via Customer Attributes, the data is stored separately and Analytics and Target can subscribe to it.
