At times, the Canon Camera Connect application for iOS may behave incorrectly when attempting to connect an iOS device to a camera via Wi-Fi . Deleting the app's saved state in the background can oftentimes correct this. This does not harm the app or the device and simply causes the app to launch with a default "state", which can eliminate many issues that prevent the app from connecting to the camera and performing correctly.
