It may be IOS 9, but when I get into just about any screen, the back button in the upper left and the Done button at the bottom of the screen do not work. I have to exit the program to move between screens when using the database.
I confirm that there are multiple reports of problems with the application on iOS 9. The investigation is in progress and fixed version will be submitted to Apple app store as soon as possible.
A new version of the application that fixes compatibility problems with iOS 9 was just submitted for review to Apple app store. Expect update to become available in a week or so.
