When sending berries to a gym when not near it, my piano berry remained on the screen and it wouldnt allow me to do anything but select it as if it were still in the Gym Pokémon Screen.
I also was sending support a message about my Dragonite that suddenly my disappeared and the game was stuck in landscape mode as I was trying to write the email in locked portrait mode.
I closed the app and I have screenshots if they help. I am using the latest iOS 10
Other than that the game is great and the updates to gyms berries and legendaries are welcome
