It's been several days now since I claimed the offer on Twitch and I still haven't received anything.
I have tried un-linking my account, re-linking it, signing out, signing back in, I even tried claiming the offer in the Steam overlay to make sure Brave wasn't blocking it with the shield. Nothing has worked.
I contacted DE support and opened a ticket, but to no surprise, they just told me to do everything I have already done (unlink and relink) and closed the ticket. They also tried telling me that if the offer was claimed on a different account they can't do anything for me. Well, I have only ever had this one account since closed beta so I know it's not a problem on my end.
It's clearly a promo problem with either DE or Twitch and it's going to be a while before either of them want to address it.
Twitch recently just implemented a new dashboard to the site, this may have broken something for people. What I don't understand is how some people were able to claim it with no problem while others have done the same steps and haven't received anything.
