Thanks, @AlexRig. Even though we can't verify this from our side, that sounds like Google believes that your email address has had a subscription before (perhaps when it was branded YouTube Red). You might wish to verify this by clicking on your profile name/icon on YouTube and Purchases and memberships.
If a previous subscription is showing there, you should be able to use the Boost via an alternative YouTube account (or you could perhaps set up a new one just for the purpose of utilising the free 4-month membership).
Please let me know how you get on.
Hi, @chrismireya. I'm not sure whether you've seen this yet but, as you're based in the US, I've addressed this matter in the thread below:
I hope this helps.
@chrismireya it was the same for me, YT has always offered me a 2 month free trial of Premium. This is not the same as Samsung Boost though, it's a YT offer.
What I had to do to get the Boost entitlement:
1. On YT web app click your profile pic > Help > Contact YT Support for Paid products
2. Explain to the service agent that you're getting an error with your code from Boost
3. Send them screenshots of the error message, Boost offer and purchase invoice
4. He couldn't do it himself and had to raise a ticket and asked that I give 'feedback' through the app citing the same case ID that he provided
5. I got an email the next day saying to signup for the 2 month free, tell them once done and they will add an extra 2 months
That was it, and now I have 4 month free with my Samsung email being different from my existing YT one:
