Hi, I am using chartboost to promote my own apps. I have chartboost showing on my first UI view after startup. On iOS teh ad will show the first time the app is run. Any new execution of the app does not show the ad. And yes I have killed the app task before running again. If I delete the app from the iPhone and reinstall then the ad will show on first execution. This does not happen on the Android. On the Android the ad will show every execution. Is BB saving something to UserDefaults on iOS which is preventing my ads showing again on first page? EDIT : I have just tested this on a previous app I did and getting same issue. - Android will always show my first page ad on every execution. - iOS will only show first page ad on first execution after install.
