Uninstall / Reinstall
If you you are seeing a blank screen like the one here, then most likely it was due to an error with the way the app handled a recent update.
So far, the only way that we have figured out how to recover is just to uninstall / reinstall.
Once you uninstall, you can reinstall in the App Store here:
Go to the Flight Crew View listing in the iTunes App Store.
If you are still seeing the blank screen after reinstalling or if you have any other questions, please send us an email at email@example.com .
