While the initial download from the app store (Facebook, Google Play store, Apple App Store, Amazon App Store) can be quite fast, other files like graphics for the tiles are downloaded when the app is first launched. We periodically add new graphics which will need to be downloaded when the app is launched.
Solution? Wait patiently for everything to fully download. If the loading lasts for more than 2-3 minutes, restart the app/page and try again.
If the issue persists, please contact our Support team.
