"[Bugs] Cannot exit the game properly after today's update"

#PokemonGO: Ever since I "updated" Pokémon Go, the back button on my phone does not trigger the "do you want to exit the game" message. The button flashes on my screen indicating that my phone registered that I tapped it, but the game does not exit.The only way I can now exit the game is hitting the task manager button and closing ALL apps!This is on a Galaxy s8.Has anybody else ran into this problem after the update? via /r/pokemongo http://bit.ly/2GSPYwi
