A glitch where all the nearby Pokémon disappear

For some reason randomly, all the nearby Pokémon disappear. This has been happening since the last update a couple of days ago and is really annoying. I am not even driving and thats the problem. My character isnt running wildly or teleporting around but it still locks up. Besides that, it is an amazing game.
