So there's a pretty glaring problem with this game.
The GPS is able to find my location, but after that I can't move at all. What I usually have to end up doing is repeatedly close and re-open the game, and it's pretty annoying. All the "fixes" online are just patronizing bull*bleep*. Oh, I have to have GPS on and be connected to the internet? Well gee willikers! Wish I thought of that!
