Did you reboot the iPad with my steps yet?And you open the app name called Camera right?Please reply at the box below. Thank you,
Sorry about that. This is an issue with any new iOS update as manufacturers need time to update their apps in order to make them work with the new iOS version. Usually, you want to wait for the update, and/or check if all your existing apps work with the new iOS first before updating.I checked and I found that the app Canon CameraWindow work with iOS 8, so you need a compatible Canon camera.Compatible models:
