I haven't used the new ad manager in a while and while I was in the Power Editor I used to be able to upload a custom audience with user ID's but it looks like I am no longer able to do that. I continue to not be able to click on the "Create Audience" and also "One or more app IDs are not connected to your account." Can anyone assist in creating a custom audience successfully? Thanks. Also I am trying to upload a TXT file with the user IDs I do have.
