EDIT: We have ended the staggering of log-ins, and all players can now log-in immediately.
The Steam version of "Yu-Gi-Oh! Duel Links" had a brief emergency maintenance in response to the server load created by the update to the Shop information.
Due to this, we are currently staggering log-ins.
We appreciate your patience and understanding.
Thank you for playing "Yu-Gi-Oh! Duel Links."
