The dealer did not Blackjack also.
The dealer had a 3 card 21, not a Blackjack.
I know. The second part is just a mistake I found.
Player BJ + Dealer BJ = push
Player BJ + Dealer 21 = Player Win
We know this, they don't.
Everyone know about that basic rules. I think it's more likely to technical fault which it's accidentally or we can say it's a bug? Mistaken algorithm.
Never happened to me the case like this btw, i just wish fj could clarify and solve this problem asap .
