Game crashes and glitchy

Game has been crashing on me quite often ever since the update last week, 4 times in the span of 20min. Also, the new feature to feed my Pokémon berries that is in a distant gym, is not working. It keeps giving me an error message to walk closer to interact with the gym. Isnt that the whole point of the new feature? So that I can do it remotely, when I am unable to walk to the gym?
