[EDIT] As of May 23rd afternoon, we believe the problem is resolved. However we are still monitoring the service to see if there could be other causes. Thank you!
Greetings,
We are aware that the game has become laggy and unstable in the past 24h.
We are currently investigating the issue with our hosting partner in Australia, Amazon AWS, to identify the source of the problem. Note that this is a network issue and not related to the game application.
We hope to solve the problem as soon as possible and will update you once the service is back to normal.
Meanwhile thank you for your understanding and patience 🙂
