Same here watched both on twitch and Steam. Watched Tennocon from start to finish and never got Gara prime for either of them, talked with Twitch support and Amazon support and even DE. Everyone is just telling me to talk to the other because "it's not their responsibility to handle it"
I am very disappointed with the way this was managed, I and many others were and still are qualified for the rewards just like everyone else but no one is taking responsibility or action.
