Gotta catch 'em all. It's the itch you just can't stop scratching -- and one where a wave of unofficial Pokémon Go apps and web-based maps helped clue you in on exactly where those Jynx were hiding. Unfortunately, alongside an app update last weekend, the team behind the app shut down data access to third-party services like PokeVision. It released a statement to users on its Facebook page, saying these services were "interfering with our ability to maintain quality of service for our users and to bring Pokémon Go to users around the world." It added that the huge number of users has had an effect on its roll-out plans.
