Everyone writing complaints about this game are so darn impatient(especially when complaints involve tracking). The company said they were repairing the tracking system, so relax and give them time.
When you have so many million players playing a game and breathing down your throat, yeah, you’re going to run into growing pains. You can still track Pokémon (a bit more vaguely, but still possible). Part of the fun is just going outside and wandering around. Whenever I learned about poke vision and the like, I shrugged my shoulders. To those who complain about mobility impaired, that’s when you just ask a friend or get a taxi to drive you around (like kids are already freaking doing). Buy lures and incence, go outside, explore, and have fun, like the intention of the original game.
