With version 1.1.1, after adding the messaging lib, I have to add UserNotification.framework manually to the iOS project, and our app does not load. It gives a black screen. In the debug console, it doesn't give any error message.
Device: iPhone 6+
OS: 9.3.2
It works fine on iPhone 6 with OS 9.3.5 and all other iPhones that we have running OS 10+.
