The first time the app is used it has to download a large amount of data before the game is playable and depending on your internet, it could take anywhere from 10 minutes to about an hour.

If your app continues to load very slowly even after the intial data loading and your phone is very low on space, your phone may be automatically clearing that large amount of data to make room, forcing you to re-download that huge amount of data every time you open the app.
