In Pokemon Duel, why can't I progress beyond Hotel Elysium?

Question

I beat the hotel owner (Number 7) but it still shows the other hotels are locked. Is the next part not available yet or do I have to meet certain requirements to unlock the next hotel?

Comments

I can not pass hotel Elysium either. I've seen players who I think have passed, wearing masks I have not seen in the previous hotels.

Answer 1

According to Serebii, you finished thus far.
Congratulations!
