Why does my app close or crash without warning sometimes?
All apps can get worn out and begin to misbehave sometimes – depending on your device, it should be an easy fix. Start by closing the app completely, and restarting it. Otherwise, restart your device. You may also find that closing any background apps can also help. If all else fails, you can uninstall and reinstall the app (you won’t be charged again!). iPad users may also benefit from disabling ‘Multitasking Gestures’ in their general settings, which can be triggered when lots of small fingers are tapping the screen!
