POKÉMON fans have been rushing to play the latest game from the series, but some have encountered an error.
People waited a long time for its release, but some players have been let down by its launch.
Pokemon Sleep is the latest free game from The Pokemon Company, and is available now for Android and iOS.
It is less of a game and more of an app, and has players tracking their sleep while collecting cute Pokemon.
Sleep asks you to turn your phone face down on your bed while you sleep, where it uses microphones and movement to detect how long you sleep for and how good your sleep quality was.
