I’m having the same issue. Did you continue to enter in the code provided by twitch?
I click the link from twitch notifications with the code, the link directs me to the bnet page where you redeem a code. I enter the code twitch gave me and it says, “we can’t process this code at this time. Please try again”
I don’t have my PlayStation account connected and I’m not sure it would be an issue as they claimed it’s only for PC I think.
Also, was your code 21 characters long? I see on the bnet page, there’s 16 X’s, but I’m aware it could be a place holder. Just kind of a bizzare situation and it doesn’t seem like it’s a frequent issue. All help is appreciated.
Edit: User error. It specifically says to go to account overview to redeem code, which I did not do. Kinda weird the twitch link wouldn’t let me redeem the code.
