I received – I assume – the same email as you regarding the 40% extra rakeback today. However, it seems like this promotion isn’t working. The email states, "You will receive the 40% additional rakeback through the boosted instant rakeback and the daily reward," but the instant rakeback isn’t boosted at all. For me, at gold rank, it's just the old regular 8%. Additionally, considering how there is absolutely no mention of this promotion on any of their social media, I have my doubts about receiving this extra rakeback.. I guess we'll see tomorrow.
