I've search all the forums, but haven't found an answer. I'm on iOS 9.0.2 jailbroken on both my iPad and iPhone, both are experiencing the issue. The issue is with the stock Calendar app, when an "All-Day" event is entered it automatically spans two days. If I change it to show both the correct same day, it jumps back to two days when I click Add. If I boot into safe mode the All-Day event enters correctly. Does anyone else have this issue? Is there a fix?
