Help!! I get the message you are signed in but not a user

user_201791, Hi there! Thanks for taking the time out of your day to visit XFINITY for help with signing in as an authorized user to manage your account. We understand how important it is to manage your account. I am sorry to learn about this experience. We can help. By default, the account holder is designated as a primary user like the details show in this link. Here is also a great link to more details on how to find the right XFINITY ID. Please let me know if this helps.
