I am trying to get access to the account but it comes up saying:
Your DoubleClick Search authentication needs to be renewed, please log in here (log in as email@example.com). Then rerun the query.
I keep going back to the login page and putting the username and password, and it's always accepted, but I keep running into this issue thereafter.
We have access to DS via another account but it won't let me add this account. Any ideas?
instead of re-authenticating, delete the whole account under DoubleClick and start the authentication process from beginning. This should do the trick.
