While we were able to address the previous issue wherein players were unable to access instances, we conducted another investigation and confirmed that the issue was ongoing for a number of players.
We have been able to identify the cause of the issue and have started the recovery operations. Once we have tested the fix, we plan on conducting another emergency maintenance. We will follow up once we have a better idea on the time frame of the maintenance.
We sincerely apologise for any inconvenience this may cause.
