Clyde's wife has an iPad and it's switching between apps accidentally. Leo says iOS 12 has a new interface that enables users to swipe left or right and change apps. It's a new feature and she may be doing that by accident. It is possible that there may be a stuck button that's causing it. Leo recommends going to the nearest Apple Store and setting up an appointment with a Genius. She should describe the problem, and they'll show her what's going on. They may even have one-on-one training.
