I added Stream Saver, can I cancel non-Xfinity Nexflix now?

Hello user_g596bs, thank you for taking the time to post here in our Xfinity Community forum. We are happy you're here, and happy to help. If you are connected to your prior account in your new accounts, then yes, you should be able to cancel billing from other providers, as it is similar to switching phone providers. You still use the same phone number and email address, you just pay a different company.
