Got this issue for two devices we were using with versions ios 9.3.3 and ios 9.2. But this issue was not coming for a device running ios 8.2 and another running for iOS 10 (tested on 10.3)

Issue occurred on devices with 9.3.3 and 9.2 on every fresh install. But restarting the device seemed to fix the issue. Although that is NOT a solution we can propose to customers.

On the console logs for the system we got 'Unbalanced calls to begin/end appearance transitions for SBBannerButtonViewController' message when this occured.

This seems like an issue with some devices having 9.x versions and should be working fine for devices running iOS 10.0 and above.
