Netflix I already have an acct

Hi 😃Bundling monthly bills makes things a lot easier. Netflix on Us is a great bundle AND it saves save money!

When you sign up for the Netflix on Us feature, you get a text message with a registration link. That link will ask you to sign in to your T-Mobile account and then direct to the Netflix login. There you can sign in to your existing account or create a new one. After that process, T-Mobile will be listed as your payment method on Netflix. 

I'm not actually answering your question, but just an FYI. I'm new here too, and same situation. Just know that the free netflix is with commercials (which is fine for me). Extra $ for ad-free. Also, app doesn't work if you use a chromecast dongle. But, you still can cast from Netflix online through chromecast. That's it. Take care.
