New Feature Arriving
On August 27th, 2019, Niantic officially deployed the Adventure Sync: Nearby feature worldwide. The feature was only previously accessible in Australia and New Zealand.
For many players, this feature is just an Unown and Gible notification system, which is welcomed but not entirely useful. This feature will become important on September 16th, when the new generation of Pokemon, Gen 5(Unova), arrive in the game.
