Gracie yet in Pokemon Go? If so and you use older devices for this then you have a problem. Some of them will be denied access to the game, and Niantic will soon block accounts.

Pokemon Go at a more or less crazy pace is further developed. The craze for catching virtual creatures has long since passed, but some persistent enthusiasts continue to travel next kilometers in search of new generations. People who play Pokemon Go on some older devices may soon be very surprised. Niantic reported that Pokemon Go will stop working on iPhone 5, 5C and iPads from the 2nd to the fourth generation and the first iPad Mini. None of the above devices can be upgraded to iOS 11. And that's what the system will require to play.

The changes will take effect on February 28, 2018. Interestingly, however, owners of these devices will not be able to log in to their own accounts. All those who play Pokemon Go and have such smartphones or tablets should be careful about the possibility of depriving themselves of items and coins. You will need newer equipment for further play . The changes are related to the introduction of AR capabilities, i.e. the actual size or movements of the Pokémon. These novelties use ARKit and require iOS 11 to be installed.
