I keep receiving this error after authenticating the login to multiple media placement accounts. Error message is below then the sidebar goes blank.
Log out from AW failed: ScriptError: Authorization is required to perform that action.
Sorry to hear that this is happening. Please try the workaround noted in this article as it may help with this:
If that doesn't, then I need to know your user account for Supermetrics (aka your Google user account), so I can do some additional checking on the issue.
