A:AnswerI was just able to download the HBO GO app using my new device and it automatically worked without having to setup an account or needing any CC info. Hope this helps.
A:AnswerThe promo code gives you a 30-day free trial to HBO Max starting from the day you redeem the code. but your code will have an expiration date and needs to be redeemed prior to that date. My code expires about 60 days after the purchase of the tv.
A:AnswerBe glad your credit card wasn't immediately charged like mine was for an HBO product I didn't want. You can only enter the code once and it is case sensitive and spaces must be entered exactly or it will not be recognized. Check to make sure it was entered exactly. If it wasn't you should be able to enter it properly again since you never really got it right the first time. Check your email for the code that was sent or your receipt. I hope that helps.
