All systems and devices
In almost every case reported to us, the reason for the app crashing when launched is due to corruption during download or an error during installation. The easiest and quickest way to fix this problem is to:
- Delete the app from your device.
- Log in to your account at the App Store (Apple) or the Play Store (Android).
- Re-download and reinstall the app (you own the app, there is no additional cost).
Apple iOS users
Apple has instructions on their web site for helping with these kind of issues, but the first thing to do is back up the app to your computer or the cloud by performing a full sync. Delete the app from your device, then shutdown and restart. Perform a sync to reinstall/restore the app and it should work fine.
