How do I redeem Netflix on us if I have an existing Netflix account

They really need to fix this. I've been trying fir an hour to get it to work and it's not.

I just did this.

Go into your primary line.

Click Manage-Addons.

You will need to add one of the Netflix addons you see in the list (if you haven’t already)

Once you add it.. or get into the details if you already have it.  You'll see a button that says "Go to Netflix" 

This will take you to netflix and ask you to login to netflix.

Once you login, it might just take you to the netflix screen for watching videos.  If this happens, go back to tmobile and click the "Go to netflix" button again.

Eventually, you will see a message that says “Link your tmobile account”  

Follow that through and link it.

Then go to your netflix account page and check your billing info.  Should say that its being billed through your tmobile account.

Every time I click on “If you're already on a plan with Netflix included, sign up for Netflix aquí." it just reloads the same page.  No way, I could find, to actually get this set up.

I get Netflix with Xfinity.

Will T-Mobile just give me the credit?

I want to transition from my Sprint Plan to Magenta +…  

I notice Hulu is gone though.. that was free with Sprint. I suspect I lose that in transition to Magenta +?

I also have AAA and assume they just add another year onto membership?

I followed instructions from majestiq and it worked for me. I even verified on Netflix where my billing now says "Billed through T-Mobile package
