Fun but theres a problem

I love the new gym system with Raid Battles inclusion since it gives us something new to do until we get the 3rd gen Pokémon like Treecko, Torchic, and Mudkip. However, theres a problem that keeps cropping up whenever I try to feed a berry to a Pokémon in the gym and I receive an error no matter how many times I close and open the app. Please fix this!
