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.

To delete the saved state for Canon Camera Connect, do one of the following:

On an iOS device with a Home Button (prior to the iPhone X):

1. Delete the app's saved state by double-clicking the home button, scroll through the saved states of the apps and find the Canon Camera Connect app, then swipe it up to delete it.
2. Re-launch the app.

 
On the iPhone X or any iPhone after which has no Home button:

1. Swipe up from the bottom to the middle of your screen and hold until you see the App Switcher.
2. Swipe left or right to find the Camera Connect app.
3. Swipe up on the Camera Connect app to delete it's background saved state.
4. Re-launch the app.
