Initial download really takes a lot of time. And even though you said it's not your connection that's the problem, it's still a factor.

In general, it depends on your internet speed, your internal memory, your device's RAM, and sometimes, even your OS (some new OS are having problems with the game, but I recall they've already fixed it).

Current proposed solution: Be patient.
