Hello, Tamers!
This is Dats Center.

Following an internal review regarding the use of the promotion package items sold on January 28, an error was identified. 
As a result, a temporary account restriction has been applied to some accounts that used these items.

We are working quickly to resolve the issue, and all restrictions will be lifted as soon as the problem is fixed.
We apologize for the inconvenience, and further updates will be provided via official announcements.

Thank you.
