Greetings, Lords around the world!
This is GM Varhya.
The issue where rewarded ads were not loading properly has been fixed upon 6/30(Wed) 6:30(UTC+0).
We are having an issue where rewarded ads are unable to be loaded in-game and thus displayed as [Being Prepared] on Android devices.
After a checkup with our Ad-network (Google),
we have confirmed that the cause of the issue was from technical error from the Ad-network, and all games utilizing the same network are experiencing similar issues.
We apologize for the inconvenience,
and will update the current announcement upon resolving this issue.
Thank you.
