We’ve temporarily disabled the ability to send Berries to Pokémon defending Gyms through the Pokémon info screen to resolve an issue.

Some Trainers may experience a bug where they are unable to assign a Pokémon to a Gym shortly after the Gym was claimed for their team. Attempting to assign a Pokémon returns the error message: “The Gym is under attack! Try again later.” We are actively working to resolve this issue.
