From December Nth (app Version 3.8.0, Buildit Version 0.18.0), the World thumbnail sizes will change to 1024x1024pt(1:1).
Please update your app and Buildit to make sure you have the latest version.
*For Worlds already published, the thumbnail will automatically be cropped to 1024x1024pt(1:1). Make sure you update your thumbnail before the update!
*The review process will not be affected by this change for the Worlds that are submitted before the effective date. However, keep in mind the thumbnail will be cropped to 1:1 ratio.
*To change the thumbnail to an existing World, download the newest version of Buildit (Version 0.18.0) and reupload the thumbnail. To check the new 1:1 ratio thumbnails, update your ZEPETO app to the latest version!
We will continue to improve ZEPETO.
