Loading issues are often caused by not having enough space on your device for Create and Play to load all of the colorful content waiting to be explored!
Try clearing up some space on your device (at least 2.5GB), you can do this by deleting pictures, videos or other apps. The app may take some time to download even after clearing up some space. Check back in to see if your colorful experiences have finished loading!
