IV & MITM
Niantic seems to have changed the way the app calls the data, what this means for PokeGo++ 2.0 is that all of the Man-in-the-Middle (MITM) dependent functions have to be adjusted.
This effects IV, IV notifications, and the map.
IV on jailbroken devices is free for all. IV on non jailbroken devices is a Donor Perk.
