Thanks for the bug report. What device are you using? And which version of Android? The loading does take a looooooooonnnnng time (that's a function of the PhET simulations as far as I'm aware) but it should load the simulation within 10 seconds on most devices.

Also, can you use a PhET simulation from the phet website https://phet.colorado.edu/en/simulations/category/new (and if so, how long do they take to load on your device). With your help I hope we'll manage to find and fix the problem.
