Hello,
So sorry you haven’t received any official word yet on the status of the Linux client. The Dev team is fully aware of the issues facing Linux users and will provide a client shortly after finishing up some work regarding the recent update to Generation IX.
I understand that you may be frustrated over not being able to play and wasted time during the event, but it’s solely in the hands of Devs and their time. All I can help you with is letting you know I personally tagged them and informed them of the issue, they did respond, but as I said, they are working on critical work following the latest update.
As soon as a working Linux client is released, I will be quick to let you know.
If you have any further questions or concerns, please let me know.
