With the new patch, some users such as Toki767 have started to be able to test the new form of tracking on Pokémon GO. With the new tracking system, alongside the Sightings which may show Pokémon in the wild, areas may come up which showcase a Pokémon and their nearest PokéStop. If you tap them, the game will zoom out and show you the location, allowing you to properly hunt them down. They should be around 700 feet from the player. If you move out of range, it will disappear and if the Pokémon flees, you will get a notification saying so. It’s currently unclear how close to the PokéStop each Pokémon is to be. This is still in testing which is why not all players will be seeing it so things may change before it’s rolled out to all players.
