Troubleshooting: App crash immediately on launch
This type of immediate crash is an issue with the iOS operating system and not the app. You will find this problem is relatively well-documented in Apple user forums, where the following advice is generally given:
- Power the device off by pressing the power button until you get the slide lock to power off. Turn back on and retry.
- If your device has a Home button, force restart the device by pressing the power button and the Home button until the screen turns off. May take a few seconds to power off. Turn back on and retry.
- Delete the app off the iPad by a long press on the app icon > 'Remove App' > 'Delete App'. You would then need to re-install the app through the App Store and reconfigure app settings.
- Factory restore the device using the steps outlined here: https://support.apple.com/en-us/HT201252
