If your Feeder still has food inside but games keep stopping, it is most likely due to dust blocking the IR sensor & preventing the Feeder from seeing food drop down the chute. Try cleaning the sensor from dust with a lint free cloth. You can access and clean the sensor by inserting you lint free cloth inside & up the chute. The sensor is on the side wall towards the top of the chute (see photo below).
Another work around for this issue is to turn off the setting "Stop game automatically" in the settings menu.
To turn off the "Stop Game Automatically" setting, navigate to: User Profile (top right on home screen) > Settings > Toggle Off "Stop Game Automatically"
