While this is the last of the temporary bundles, we’ve recently made the following changes to Pokémon GO that’ll help you get items more easily!

• Buddies can now bring you Gifts from PokéStops! Send Gifts to friends, and receive Gifts in return that you can open to receive items like Poké Balls, Berries, and more.
• Gifts are currently rewarding more Poké Balls.
• You can get a daily bonus Field Research task without having to spin a PokéStop, which you can complete to earn items.
• The distance from which you can spin a PokéStop has been temporarily doubled.

We’ll continue to develop features and updates to make Pokémon GO an enjoyable adventure wherever you can play.
