I frequently face the error message “ERROR IMS SSO Failed: Unable to access user IMS session” when access Analytics via Marketing Cloud. So far, the only workaround I have found is to remove adobe cookies or open a new browser window in Incognito mode before signing in to Marketing Cloud.
Has anybody faced this same challenge accessing Analytics?
I checked our bug reporting system, and there are several causes behind this issue, most different to each organization. If you see this issue, I would recommend reaching out to customer care so we can get it to engineering to resolve.
